What is Python?

Python is an object-oriented, high-level, interpreted programming language with dynamic semantics. It has a rich set of high-level in-built data structures (data types) which are combined with dynamic typing and data typing. It makes Python a very popular and attractive programming language for rapid application development, and scripting. It is simple, easy to learn, and readable and Python's codes are smaller than codes of other programming languages like C, C++, Java, etc. The codes and relatively less indented which make the code readable/editable for the programmers all the time.
