Does anyone out there using Python? What are the uses of such language? Is there a software or a known program that uses this language?

Python is probably one of the few programming languages which is both simple and powerful. This is good for both and beginners as well as experts, and more importantly, is fun to program with.
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.
Guido van Rossum, the creator of the Python language and python is open source you can go to Python Programming Language -- Official Website and download the python.
