Key Features of Python

Published

on

Python is a defined high-level programming language perceived general-purpose programming and many more. Designed by Guido van Rossum and initially published in 1991, Python has a design philosophy that features code readability, prominently using important whitespace. It proffers constructs that enable clear programming on both short and wide scales. It is used for web development, software development, system scripting, mathematics. Python can be handled on a server to create web applications. Python always used for adjacent software to create workflow. Python can connect to database systems. It can also read and modify files. Python can be used to manage big data and implement complex mathematics. Lastly, Python can be applied for rapid prototyping or production-ready software development.

Python gives many useful features which make it successful and worthy from the other programming languages. For example, it promotes object-oriented programming, procedural programming methods and implements dynamic memory allocation. We have listed below a few fundamental specialties.

Let’s review some significant key features of Python Programming Language:

1. Easy Language

Python is an easy language. It is clear to read, write, interpret and understand.

Python has a constant learning curve. Therefore, it is simple to learn.

Python has a manageable syntax, and Python code is easy to learn.

Since it’s easy to understand, you can easily read and learn someone else’s code.

Python is also clear to write because of its manageable syntax.

Because it is an easy language used in schools and universities to introduce students to programming, Python is for both startups and big companies.

2. Expressive Language

Python can execute complex jobs using a few lines of code. A simple example, the hello world program you type print(“Hello World”). It will take only one line to perform, while Java or C takes various lines.

3. Cross-platform language

Python can run identically on various platforms such as Windows, Linux, Unix, Macintosh, etc. For example, a Python program composed on a Macintosh computer will run on a Linux system and vice versa. Thus, Python is a manageable language.

4. Free and Open Source

Python is an illustration of a FLOSS (Free/Libre and Open Source Software). In easy terms, you can smoothly distribute copies of this software, read the software’s source code, make modifications to it, use pieces of it in new free programs, and that you know you can do these tasks.

5. Easily Movable Language:

Python is a portable language that doesn’t need to be replaced during coding between two systems. Alternatively, you can take one code to run it into separate machines.

6. Object-Oriented:

This programming language is an object-oriented language that concentrates on objects and functions. It maintains both procedures and objects oriented programming to execute the tasks manageable to handle.

7. Highly Portable

Assume you are running Python on Windows and want to shift the same to either a Mac or a Linux system, then you can easily achieve the same in Python without worrying about changing the code. This is not possible in other programming languages, thus making Python one of the most manageable languages available in the industry.

8. Highly Dynamic

As discussed in an earlier paragraph, Python is one of the most dynamic languages available in the industry now. This indicates that the type of variable is determined at the run time and not in advance. Due to the presence of this point, we do not require to define the type of the variable while coding, thus saving time and increasing efficiency.

9. Interpreted:

In languages such as C++ and Java, you have first to compile it and then run it; you must know this if you are familiar with any languages. But in Python, there is no necessity of organizing it before running it. Instead, in Python, there is a conversion of the source code to a form called bytecode.

This means the Python code can be run without emphasizing over relating to libraries and other different things.

10. Large Standard Library:

Python has a large library inbuilt that can be used while coding a program so that you don’t have to write your code for everything.  In Python, the library implies a gathering of modules where you will locate all sorts of stuff. Modules are records, much the same as books that contain functions that should be imported into your program. For Ex. on the off chance that you require to take a stab at something else for the graphics, you can check the Python Imaging Library. The Pygame of the Pyglet libraries can be used if you need to make a game. Finally, if you are amongst the enthusiastic science fans, you have a SciPy library.

From the above-written points, we now know Python has many features that make it a Programmer friendly. Things are developing with changing dates and innovation. Java which was previously the most prevalently shown language in schools and universities, has been supplanted by Python. If you are a newcomer, the motive to learn Python is that it is anything but difficult to learn. For experienced folks, it is significant because it is rapidly turning into a language of great importance.

Let’s have a look at the top Python frameworks which will not only enhance your existing skills but it will also make you an expert as a professional backend developer.

What You Need To Know About Ethiopian Coffee Beans

Published

on

By

In this article, you are going to learn more about why Ethiopian coffee beans are so interesting to learn about, and why the country is worth the visit for coffee enthusiasts around the world.

Ethiopia might not be as big as Brazil and Colombia when it comes to the production of the international supply of coffee beans, but they are well-known to be one of the best countries if you want to get coffee. Coffee enthusiasts from all over the world visit this place in order to get its own unique strain of coffee beans, and simply because the coffee beans here are also superb in terms of its growth and overall quality.

After all, Ethiopia is considered as the country where coffee itself was found, and has its deep historical roots on how it got discovered. Some may think that coffee was found in
Colombia, but the country learned about coffee back in the 18th century only. But in the case of Ethiopia, coffee was discovered way back in the 9th century. Ever since then, Ethiopia became home to a wide variety of coffee beans, where some gained international fame and even became a signature coffee bean of other countries as these countries refined their ways of cultivating it.

The Renowned History Of Coffee Beans

It is not actually official if it’s true or not, but even neighboring countries claim the legend that Ethiopia was the place where coffee was first found. Believe it or not, it’s not some trader or researcher who stumbled upon this amazing fruit, but a goat farmer! Back in the 9th century, a goat farmer accidentally discovered the cherries of the coffee bean plant when he saw his goats consume it. He noticed his goats got too energetic unlike before when they never consumed the coffee beans. afr

As a result, he got curious if it also gives the same energy-granting properties to humans. That’s why he took some and shared it to the local monks in this place. Of course, they never know how to brew the fruit yet, so they consumed it first and realized that it can really grant them energy in a safe way. Over time, the method of consuming coffee beans eventually became the popular way that we all know about: turning it into an energizing and aromatic drink. As time passed by, word spread out about the properties of coffee and eventually gained worldwide fame that we all know about today.

Personally, this story about the discovery of coffee is really intriguing because who would expect that it was a farmer who discovered the wonders of the coffee beans by accident. History surely has a lot of unusual happenings that eventually laid an impact to a lot of people even to this day, and coffee seems to be one of them if this story is true.

The Importance Of Coffee In Ethiopia

The importance of Ethiopian coffee beans is not just all about the history that it had, and not just their strains that has a fruity flavor into it. The coffee industry of Ethiopia supplies 3% of the world’s overall coffee production. It might not be as huge as what Brazil can offer, but Ethiopia is still one of the holders of the industry’s foundation. Also, the U.S. happens to be one of the top buyers of Ethiopian coffee beans which are considered as the best African coffee beans.

In terms of the geographical importance of coffee in the country, take note that there are more than 1,500 square miles worth of coffee farms scattered throughout the country that’s dedicated for the cultivation and production of coffee beans. Just note the fact that the mountains where the farms are located have an altitude of up to 2,000 meters above the sea level. This environment is enough to grow the finest quality coffee beans. But of course, this also means that some of their coffee bean strains are considered as a luxury item due to its superb quality.

Types Of Ethiopian Coffee Beans

To get to know more about the strains that they grow here, take note of the following below:

  • Longberry – These are large coffee beans that have a lot of body with a decent aroma and flavor. These are also called as Harrar coffee beans because of the region where it grows to.
  • Mocha – Mocha is a well-known flavor around the world, and is often used in sweets because of its chocolate notes. The original Mocha coffee beans are highly-prized and can only be found in the Harrar region as well.  Some also say that this the variant of the Harrar coffee bean that has a spicy note in it.
  • Shortberry – The shortberry coffee beans are high-quality beans that has a very strong flavor that has a note of wine.

Ethiopia is a go-to if you are curious about the more exquisite, or even exotic, types of coffee to try out. This is worth marking on your map if you love to travel as a coffee enthusiast, or if you just want to travel and see the specialties that each country has in store for you.

How do they make Nitrous Oxide?

Published

on

By

Before we get to how they make nitrous oxide, we first got to learn what is Nitrous Oxide? Nitrous oxide, commonly known as laughing gas, nitrous, or nos, is a chemical compound, an oxide of nitrogen with the formula N2O. At room temperature or the temperature that adapted to its surroundings, it is a colorless non-flammable gas, that gives off a slight metallic scent and taste. At elevated temperatures or above normal oral temperature, nitrous oxide is a powerful oxidizer similar to molecular oxygen. Nitrous oxide has significant medical uses, more so present in surgery and dentistry, for its anesthetic and pain numbing effects. Better known by the masses as “laughing gas”, it received this name due to the euphoric effects a person experiences after inhaling it, with this property that has led to its use as a anesthetic. You can readily buy laughing gas but only for culinary purposes.

It is on the World Health Organization’s List of Essential Medicines, the safest and most effective medicines needed in a health system. Though it became popular as an anesthetic, nitrous oxide has so many other uses. It increases internal combustion engine power, serves as an oxidizer in experiments including chemicals and rockets, and it also acts as a propellant for foods including cooking spray and whipped cream, and has multiple uses in medicine showing that it has its flexibility in uses as a chemical compound.

After learning what is Nitrous Oxide, How does someone produce said gas? The basic and safe method to make nitrous oxide at home or in a small lab was discovered by a chemist named Humphry Davy. Davy discovered that through heating ammonium nitrate, it decomposes into nitrous oxide and water vapor:

NH4NO3 (s) → 2 H2O (g) + N2O (g)

While simple, it’s crucial to gently adjust the heat of ammonium nitrate between 170 °C to 240 °C (338 °F to 464 °F). Exceeding the maximum temperature leads to rapid decomposition and the glass container to shatter due to reaching its breaking point. Use small amounts of ammonium nitrate then control the temperature with a thermometer just to be safe.

1. Place a small amount of ammonium nitrate in a test tube. Cap the test tube with a one-hole stopped. Insert plastic or glass tubing into the hole and run it into a hot water bath. The water needs to be hot because nitrous oxide dissolves in cold water, reducing the amount collected. Collect the bubbles in an inverted jar. This setup for collecting gases is called a pneumatic trough. It condenses water produced by the reaction and removes impurities, like smoke.

2. Once you’ve set up the equipment, slowly heat the ammonium nitrate. You can do this over a flame or burner. Apply heat so that it does not exceed the maximum temperature and so it produces gas bubbles at the rate of one to two bubbles per second.

3. Stop heating the ammonium nitrate before all of it has decomposed. This helps prevent overheating. Turn off the heat and disconnect the tubing from the collection jar so that water won’t flow up into it. Cover the container before turning it upright, so you won’t lose the gas. You can seal the container while it is inverted or simply cover it with a flat sheet of plastic or glass before turning it over. The gas in the container is nitrous oxide, plus smaller amounts of other nitrogen oxides, such as nitric oxide and nitrogen monoxide. Exposure to air oxidizes the nitric oxide to form nitrous oxide.

This procedure is commonly used for commercial preparation of nitrous oxide, with acid and base treatments to further purify the gas.

In 1772, another method for making nitrous oxide was discovered by Joseph Priestley and he became the first person to synthesize nitrous oxide. Priestly collected the gas produced by sprinkling nitric acid over iron filings. While an effective method, this method is better attempted in a lab by scientists because nitric acid should be used under a fume hood, with proper gear to avoid accidents. Another method to make nitrous oxide in the home or lab is to heat a mixture of sodium nitrate and ammonium sulfate. Again, collect the gas using a pneumatic trough. Heating this mixture is even safer than decomposing ammonium nitrate.

2 NaNO3 + (NH4)2SO4 → Na2SO4 + 2 N2O+ 4 H2O

The chemical reaction between urea, nitric acid, and sulfuric acid also produces nitrous oxide.

2 (NH2)2CO + 2 HNO3+ H2SO4 → 2 N2O + 2 CO2 + (NH4)2SO4 + 2H2O

Here are tips to prepare nitrous oxide safely:

– Never exceed the temperature when heating ammonium nitrate over 240 °C or 464 °F.

– Turn of the heating apparatus before the last bit of ammonium nitrate has decomposed.

– Use the highest purity ammonium nitrate available for the safest method. Pure ammonium nitrate is more stable than ammonium nitrate with impurities.

– Perform the project in a lab or in a well-ventilated area if at home. Overexposure can be fatal.

Due to the dangers difficulty involved in making nitrous oxide yourself you will most likely want to just buy nitrous oxide from an online seller and have it delivered to you.

How to Become a Life Coach

Published

on

You may have a passion for helping others pursue what makes them happy in life. Whether giving advice on a career change or how to overcome an obstacle, you thrive at helping people. Friends may have mentioned that you’d make an excellent life coach, and you’re ready to give it a shot! 

To follow your dreams and become a life coach, here are some tips on how to get started.

1. Figure Out What Your Goals Are 

Before diving into building your business, first, you should set some goals. 

It’s essential to keep in mind that with any business, getting things rolling takes time. But the good news is that by having goals, you’ll have a clear starting point. 

So work on coming up with some personal and financial goals. An example of a specific goal might be to get 15 new clients in two months. 

Don’t make your goals unrealistic, but at the same time challenge yourself. After a few months have gone by, you’ll have a better idea of how things are going. From there, you can adjust your goals accordingly. 

2. Consider How Much You Want to Spend on Startup Costs 

Do you know how much becoming a life coach will cost? Before jumping in headfirst, it’s vital to understand how much money you want to spend. 

If it’s a side hustle for you, you likely won’t have to spend a lot. But say you want life coaching to be your full-time profession. Then, you may need to fork out more money upfront. 

You don’t have to spend a lot initially, but there are a few things you should budget for. For example, setting up a website would be a good idea. Spending money on advertising would also be helpful. 

Advertising will help you get website traffic. Setting up ads is essential so that people learn more about you and your services. So, look into setting up an account on Google and Facebook. 

It would help if you also considered getting business insurance. Liability insurance, in particular, is essential. With liability insurance, you’d have protection if you got sued for not giving good advice. 

3. Use Social Media to Your Advantage 

Advertising your services on sites like Facebook and Instagram certainly has its advantages as well. It’s effective because it drives traffic, but organic traffic is just as important! So with that being said, focus your attention on building a following on social media. 

Social media is tricky, though. It’s impossible to be active on every social media platform. Being too involved often results in getting burned out

So, it’s up to you to do some research and figure out where your audience hangs out the most. For example, if your audience tends to spend their time on Instagram, make an effort to be more active there. The same goes for LinkedIn. 

Wherever potential customers are engaging, you should engage alongside them. If the opportunity presents itself, you can mention your services. Although, don’t feel like you have to be overly proactive. Frequently getting into a conversation with someone is enough. They’ll likely click over to your profile and learn more about you since you’ve been chatting. 

4. Write on a Blog 

As a life coach, you have a lot to offer! One way to showcase your skills is by starting a blog on your website. You can cover an array of topics, from how to jumpstart your business to how to recover from hardship. 

Having a blog on your site offers other benefits, as well. For example, you can add ads to your site and use affiliate marketing as well. Promoting products and services from other companies can earn you money.

Besides earning money, affiliate advertising has another perk. You get to share the products that you believe in with your readers! 

Having your blog gives you the power to choose what topics you want to discuss. Being in charge also gives you the final say on things like what type of products you wish to promote. 

The truth is there really are no disadvantages to starting a blog on your website! 

5. Continue Your Education 

You may or may not decide to get a life coach certification. If you do, it’ll benefit you in the long run. You’ll be able to tell your clients that you’re certified in the area you’re coaching them in. Once they learn of your expertise, they’ll likely have more confidence in you! And they may be more willing to refer you to their friends as well! 

Besides getting a certification, consider continuing your education in other ways. A few ways to soak up more knowledge are by reading, attending seminars, and going to workshops. You can also join Facebook groups and connect with other professionals in your field. 

Honing your skills is something you should focus on as it will allow you to grow. Better yet, you’ll be able to provide better services to your clientele. 


Conclusion

Becoming a life coach is no doubt a fulfilling career. You get to help people overcome obstacles and reach their highest potential. 

It may take a while for you to get your coaching business up and running. But once you get the hang of things, you’ll find great success doing what you love!

CURRENT EDUCATIONAL ISSUES IN 2021

Published

on

There are probably many things facing the education industry, some of which have persisted for years. However, in 2021, nothing has affected and threatened to cripple the whole space like the Covid-19 pandemic. Schools and educational centers have struggled to cope with the effects brought about by the pandemic. When it all started in 2020, it was panic stations all around and many students and teachers were thrown into confusion. Even though there are signs of normalcy returning to the world, some issues have been exposed more than others. Here are some of them.

1. Over 1 billion students have dropped out of school

There has always been a struggle to educate the masses, and while this was already going on, the pandemic has dealt a heavy blow to it. According to a UNESCO report, over 1 billion children stopped going to school when the pandemic hit and governments had to shut down schools to contain the pandemic. This has affected over 124 countries and accounts for over 70% of total students in schools. Of course many students have chosen to continue their education online with help from online platforms like AssignmentMasters that help many complete their school assignments.

2. Some Parents are now Homeschooling

This has been happening even before the pandemic hit us. But with the pandemic already here, parents who never thought of this have now been forced to do it to ensure their children don’t miss out on a chance to learn. However, questions are being asked about the effectiveness of this given that not all parents can actually teach. Some parents may be too busy to assign and mark assignmentholic.co.uk. Some may not even have the qualifications to do it.

3. Cancellation of Examinations

It took a while before many educational institutions could decide what direction to take as the pandemic hit our doorsteps. However, one of the toughest issues to tackle was whether to go on with high-stakes examinations or cancel them. This presented a curriculum quagmire that is still affecting many schools today. Some institutions reverted to online examination even as this presented a lot of challenges. Even so, many institutions had to find a way to do this or cancel the tests altogether.

4. Seniors in College and High School Lost Out

Even as some institutions canceled the end-year examinations, many senior students who were hoping to finish school found themselves in a closure quandary. Many who were hoping to finish their education and move on to the next phase of their lives were left disappointed and confused. This has led to many students despairing while others have sought alternative ways to finish their education. Many, however, have decided to take it on their chins and move on.

5. Too many online resources

While this may not sound like a bad thing, it may have challenges that may affect the quality of education offered. Many online platforms and groups have surfaced to try and provide a solution for those that have been adversely affected. The problem is that some of these platforms may not offer the best quality of learning needed. However, some like research paper writing services uk have been a cut above the rest in offering the best services for students and teachers. Even though some of these platforms offer quality services, the amount of platforms online has been overwhelming for parents, teachers, and students as well.

6. Inequities have been further exposed

Although this has been talked about for many years, the pandemic has exposed it even further; some schools and institutions have countless resources to offer students and caregivers while others have very little or none at all. These inequities have further exacerbated the situation. While some students can access essayontime.co.uk and have their essays done on time, some do not even have free internet to learn.

Conclusion

There are many more issues facing education today, some of which have been made worse by the pandemic. While many countries try to fight the disease and restore normalcy, the education industry has a long way to go to try and restore their own normalcy. Many teachers and students have had to adjust to many restrictions and the virus waves. As schools reopen in some countries, many questions still need answers.
