Python is an excellent first programming language!!

It's also a great "glue" language to be used by seasoned pros.

Python is easy to read, easy to program and is object oriented and can easily do a ton of stuff with very little code.

If you want to see something significant written in Python, go to EVE online website (Space game). Somewhere on their website they report they use Stackless Python in EVE.

Stackless Python is an advanced Python, which avoids programming the "stack" which is highly used in the C Language.
