WHAT IS PYTHON PROGRAMMING LANGUAGE

Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. Python’s simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed.

Often, programmers fall in love with Python because of the increased productivity it provides. Since there is no compilation step, the edit-test-debug cycle is incredibly fast. Debugging Python programs is easy: a bug or bad input will never cause a segmentation fault. Instead, when the interpreter discovers an error, it raises an exception. When the program doesn’t catch the exception, the interpreter prints a stack trace. A source level debugger allows inspection of local and global variables, evaluation of arbitrary expressions, setting breakpoints, stepping through the code a line at a time, and so on. The debugger is written in Python itself, testifying to Python’s introspective power. On the other hand, often the quickest way to debug a program is to add a few print statements to the source: the fast edit-test-debug cycle makes this simple approach very effective.

FEATURES OF PYTHON PROGRAMMING LANGUAGE

Python Features and Advantages

1. Easy to Code

Python is a very high-level programming language, yet it is effortless to learn. Anyone can learn to code in Python in just a few hours or a few days. Mastering Python and all its advanced concepts, packages and modules might take some more time. However, learning the basic Python syntax is very easy, as compared to other popular languages like C, C++, and Java. 

Let us now look at the next feature of python.

2. Easy to Read

Python code looks like simple English words. There is no use of semicolons or brackets, and the indentations define the code block. You can tell what the code is supposed to do simply by looking at it. 

We will now look into the next Python features.

3. Free and Open-Source

Python is developed under an OSI-approved open source license. Hence, it is completely free to use, even for commercial purposes. It doesn’t cost anything to download Python or to include it in your application. It can also be freely modified and re-distributed. Python can be downloaded from the official Python website.

Let us find out the next feature of python.

4. Robust Standard Library

Python has an extensive standard library available for anyone to use. This means that programmers don’t have to write their code for every single thing unlike other programming languages. There are libraries for image manipulation, databases, unit-testing, expressions and a lot of other functionalities. In addition to the standard library, there is also a growing collection of thousands of components, which are all available in the Python Package Index.

We’ll now learn about the next feature of python.

5. Interpreted

When a programming language is interpreted, it means that the source code is executed line by line, and not all at once. Programming languages such as C++ or Java are not interpreted, and hence need to be compiled first to run them. There is no need to compile Python because it is processed at runtime by the interpreter. 

Let us now look at the next feature of python.

6. Portable

Python is portable in the sense that the same code can be used on different machines. Suppose you write a Python code on a Mac. If you want to run it on Windows or Linux later, you don’t have to make any changes to it. As such, there is no need to write a program multiple times for several platforms.

Top 10 Websites to Learn Python Programming for FREE in 2022

Hello guys, if you want to learn Python in 2022 and looking for some Free Websites and free Python tutorials then you have come to the right place. Earlier, I have shared the best Python programming courses and Python projects which you can do to learn Python.

Today, I am going to share popular websites to learn Python coding for free and free Python coding tutorials from sites like Google, Microsoft, Udemy, Coursera, Educative, FreeCodeCamp, CodeCademy, Javarevisited, and much more.

But before that, if you are here then let me first congratulate you for making the right decision to learn Python programming language, the king of programming language.

Python has inspired many people to learn to code and it’s continually inspiring them. I know a handful of people who are learning Python for different reasons, starting from web development to machine learning.

I have seen new people learning Python to write web apps using Django and Flask, create a Machine learning Model using Python, and just write some handy scripts to automate the boring stuff.

Python is currently the world’s #1 programming language and its popularity is growing every passing day, thanks to Data Science and Machine learning and awesome Python libraries like Pandas, NumPy, and TensorFlow.

So, if you are also thinking to learn Python in 2022 or already started coding with Python but still looking for some free resources then you have come to the right place.

In the past, I have shared a lot of useful free Python resources like books and free courses. And today, I am going to share some of the websites, free tutorials, and portals where you can learn Python for free.

Learning from free resources is fantastic as you don’t need a credit card or no need to pay for the course. All you need is time and hunger to learn.

Though, it’s not easy as there are a lot of free Python resources available out there and it’s a difficult task to choose the right one. It’s like finding a needle in a haystack, and that’s where this article will help you.

Btw, if you don’t mind paying a few bucks for learning something as valuable and useful as Python, then I also suggest you check out Josh Portilla’s  on Udemy. You will learn Python quickly and in a more structured way, and you can buy this course for just $10 on Udemy’s sale

Top 10 Websites to Learn Python Programming for Beginners

Here you will find some of the best places to learn Python for free, I have handpicked these resources with a couple of Python experts.

I have purposefully chosen as few resources as possible but still with some options. Just in case if you have any other useful Python websites which teach Python development for free then feel free to suggest.

1. Google

If you don’t know, Google also has an excellent set of Python tutorials for beginners, known as Google’s Python class. This is a free class for people with a little bit of programming experience and who want to learn Python. The course includes written tutorials, lecture videos, and lots of code exercises to practice Python coding.

The first exercises work on basic Python concepts like strings and lists, building up to the next exercises, which are full programs dealing with text files, processes, and http connections.

Google itself uses Python for a lot of its projects. And, these materials are generally used within Google to teach Python to people who have just started coding or have little programming experience.

The best part of this material is that lecture videos are available on Youtube. Hence you don’t need any other account. It also teaches you to set up your own Python development environment, which does produce initial challenge but great for the long run.Google’s Python Class | Python Education | Google DevelopersWelcome to Google’s Python Class — this is a free class for people with a little bit of programming experience who…developers.google.com

2. Udemy

Udemy is one of the popular online course platforms, which probably has the biggest collection of free online courses on earth. I like Udemy because you can virtually find a course on anything you want to learn and that too for free.

Unlike , you don’t need any subscription, you just need to create a free account, and then you can enroll in free Python courses. Most of the instructors keep their course free when they first launch them so that they can get some traction, reviews, and social proofs.

But, there are also good quality Python courses that are entirely free likeand. You can join them to learn Python 3. Here are some of my favorite free classes to learn Python in depth.
