Definition



Python is an easy to learn, powerful
programming language.
It has efficient high-level data structures and a
simple but effective approach to object-oriented
programming.
Python’s elegant syntax and dynamic typing,
together with its interpreted nature, make it an
ideal language for scripting and rapid
application development in many areas on most
platforms.
