Python is an interpreted language rather than a compiled one. This means that your program remains a text file which is read by another running program called an interpreter. The interpreter follows your instructions and generates machine code on the fly, which your CPU executes.
Before you can do anything, you have to make sure you have a Python interpreter.
** Python 2.x is now deprecated, meaning it is no longer officially supported, and not recommended for new designs.**
iPython is an interpreter. There are many implementations of Python interpreter, but iPython is the dominant one.
