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."
