Python
Python is a dynamic, strongly typed, object-oriented, multipurpose programming language, designed to be quick (to learn, to use, and to understand), and to enforce a clean and uniform syntax. Two similar but incompatible versions of Python are in use (Python 2.7 or 3.x). For version-specific Python questions, please also use the [python-2.7] or [python-3.x] tags. When using a Python variant (Jython, Pypy, Iron-python, etc.) - please also tag the variant.
