Introduction to the Python programming language

Python It is a high-level programming language. Python appeared in the late eighties by Guido van Rossum, and its first release was in 2000.

Python works on all basic operating systems such as Windows, macOS, and Linux, and also works on virtual machines like Java and .NET. Python is an open source and free language.

Python comes installed on most operating systems such as Linux and Mac, but the Python version installed on the operating system may be an older version. Therefore, it is always better to install the latest version.

Why Python?

Python is one of the most famous programming languages in the world. Python is a programming language that is easy to learn and write. There are also many other good reasons why Python is the best choice for any programmer:

• The Python language is open source which means it is available for free.


• Python language is simple and easy to learn


• The Python language is versatile and can be used to create many different things.


• Python has powerful development libraries that include AI, ML, etc.


• There is a huge demand for Python and guarantees high salaries

What can you do in Python?

• Web Development


• Game Development


• Building embedded systems and robots


• Data Science and Data Analysis


• Machine Learning and Artificial Intelligence


• Scraping Web Dredging Apps


• Business Applications


• Audio & Video Apps


• CAD Applications

Why did I start learning Python and why do you also have to learn Python?

If you're running a small business or operating independently, you're probably dealing with data in one form or another, whether it's building websites or tracking customer data – hence learning programming in Python can help you increase your productivity – for example, in your work you're doing a time-consuming task (like pulling data from a website to add to a spreadsheet) using a little bit of code that can save a lot of time, rather than of doing this task manually.

Learning to code can also be a lucrative career choice. In fact, the average salary of a Python developer in the United States in 2021 is $110,840. And of course this is a very good return on the time invested in learning programming.

Why is Python easier to learn than other programming languages?

Python is a good language for beginners: when Guido van Rossum started creating Python he wanted Python to be as understandable as simple English. And easy to read. In addition, Python has a clearer wording that doesn't require many lines of code such as C or Java to get similar results.

For example, compare these two codes, both of which display the same result "Hello, World!" on the screen. Python code is shorter and does not require complex syntax.

python:

print('Hello, world!')

java: 

class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}

Are there large companies and websites that rely on programming in Python?

Some large companies like Google, Dropbox and Instagram rely heavily on Python. Just take a look at the following list (which is not exhaustive of all Python-based sites).

• Spotify has redefined music streaming through Discover playlists and smart radio channels thanks to data insights aggregated through Python.


• Citigroup is used. Many investment banks train their analysts at Python so that they perform valuable risk assessments from algorithmic trading models.


• CERN Large Hadron Collider uses Python to analyze customer data and experiences


• Uber uses Python to leverage Python-based machine learning and data science frameworks to build algorithms that help it connect drivers and passengers.


• Netflix uses the Python language to make sure movies stream non-stop.


• Even the Google Home Assistant works on Python through human language processing technology.

How to start learning Python?

Each person's brain works differently from the other, which means that each person learns differently. So, the best way to learn Python is to do everything you read. Now just open the computer, install Python and start learning Python.

If you are a beginner in programming, you have to be patient in learning and you will reach what you want, God willing. Python is the easiest way to get into programming (or at least one of the easiest ways). The best way to learn Python for non-programmers is to go slowly and patiently.

Think of an app that you can create first and have your learning plan revolve around it. Try to create a simple website with Django.

If you receive an error, it means you're going in the right direction. If you make a lot of mistakes, that's great – because mistakes are what teach you to do things right. Every mistake should make you excited and eager to find a solution. The best learning is through errors and exceptions.

Learn syntax along the way. Don't spend a lot of time learning syntax on your own. Create a project with an IDE like PyCharm, and start coding. You will learn about syntax when you write more code.

Start with a simple project and improve your level while writing code. Then include functions to this The project that are more complex.
