Python is a popular high-level programming language. It is a powerful language used for
general-purpose programming. Python was developed by Guido van Rossum. He started
applying Python in 1989. Python is extensively used to develop:
Games Websites
Graphical User Interface programs Web applications
FEATURES OF PYTHON
Following are the features of Python:
Easy to code: It is very easy to write programs in Python as compared to other high-level
programming languages. This is because the language used to write Python codes is similar
to the English language.
Open-source language: Python is a free and open-source programming language. An
open-source language is one which can be easily improved and distributed by anyone. You can
download Python free of cost and use it on any operating system such as Windows, Mac or Linux.
Object-oriented: Python has an object-oriented approach. This means that the programs
are designed using objects and classes that interact with each other.
Integrated and extensible language: We can easily integrate Python with other languages
such as C, C++. We can also write and compile a Python code in C or C++.
Interpreted language: The code you create in Python is executed line by line which makes
it easy to correct any errors. On execution, a Python code is immediately converted into an
intermediate form. This is known as byte code. The byte code makes it easier to execute or
run the code in future.
