You should also read "https://www.python.org/dev/peps/pep-3147/".
It mainly explains why "pycache" has been introduced
but as a side effect, it points out a bondage between
the "*.pyc" files and the major Python version: it is very likely,
that a major Python version will not accept "*.pyc" files created
by another major Python version.
