Python is a multi-paradigm, dynamically typed, multi-purpose programming language. It is designed to be quick to learn, understand, and use, and enforces a clean and uniform syntax. Please note that Python 2 is officially out of support as of 2020-01-01. For version-specific Python questions, add the [python-2.7] or [python-3.x] tag. When using a Python variant (e.g. Jython, PyPy) or library (e.g. Pandas, NumPy), please include it in the tags.
