ENV SUMMARY="Platform for building and running Python $PYTHON_VERSION applications" \

DESCRIPTION="Python $PYTHON_VERSION available as container is a base platform for \

building and running various Python $PYTHON_VERSION applications and frameworks. \

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."
