Introduction to Python programming language
All the applications or software that run on computers and mobile phones are made with the help of some programming languages. Nowadays you will get to see many programming languages like java, C, C++, python, Swift etc. These are all computer languages written and understood by developers in order to develop any program. Every language has different features which make them unique and different from other programming languages. As the technological world is changing, many changes are also taking place in these programming languages. Python is one the popular programming language which provides great features to the users.
Today, through this article, we will learn whole-heartedly about python programming language.
So Let's dive in..!
What is python Programming language?
Python is a powerful, easy to learn and an open source Programming Language a high level general purpose programming language which means that it can be used for developing other types of software and applications besides web development. And object oriented approach of python helps the developers or programmers to write logical and clear codes for different projects.
It is a dynamic programming language which supports the feature of garbage collector. Python is one of the most popular and fastest growing programming language. In the development of python there are no compilation steps are involved which makes the development and debugging quick.
History of Python Programming language
Now let's discuss about the facts and history related to Python programming language. In 1980, Guido Van Rossum started the development of python and in December 1989 implementation of python was begun at Centrum Wiskunde and Informatica (CWI) in Netherlands. Python was ultimately released in 1991. The idea of developing Python programming language was taken from ABC programming language, in other words we can say that Python is the successor of ABC programming language. Python 1.0 was released in 1994 with some added features, then in 2000 Python was released with new features and after that Python 3.0 was released in December 2008.
Why it is called Python Programming language?
You might also be wondering how Python got its name. So here is the answer, Python got its name after the name of Monty Python. There is a fact behind the name of python. During the implementation of Python, Guido Van Rossum was reading the published script of famous BBC comedy series that is "Monty Python's Flying Circus". And Van Rossum wanted to choose a mysterious, sort and unique name so he decided to choose the name Python after "Monty Python's Flying Circus" comedy series for their programming language.
Features of Python Programming language
There are many features that makes Python famous and valuable as compared to other programming language. Here are some of the essential features of Python are listed below:
