The .pyc files are created on the fly, if they are missing or outdated and
the directory can be written to.
Generally, you would not include them in a source archive or distribution.
Binary packages may contain them.

While Python2 places .pyc files in the same directory as the source file,
Python3 creates a sub-directory "__pycache__/".
