Questions tagged [python]
Python is a multi-paradigm, dynamically typed, 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 commonly in use, Python 2.7 and 3.x. For version-specific Python questions, use the [python-2.7] or [python-3.x] tags, or more specific [python-3.6]. When using a Python variant (i.e Jython, Pypy, etc...), please tag it.
