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.
More definition
Python is cross platform (for many platforms).
The standard library is huge, very useful, and is
very well documented.

Many companies make significant use of it
Google uses it for a lot of their internal software
projects
David Bagget (speaking Tuesday) uses it in his
start up company
