No, the __main__.py module is used to invoke a package:
$ mkdir mypackage
$ echo 'print("Hi")' > mypackage/__main__.py
$ python3 -m mypackage
Hi
In Python 2 you need an __init__.py module to run the above example:
$ python -m mypackage
/usr/bin/python: No module named mypackage
$ touch mypackage/__init__.py
$ python -m mypackage
Hi
See also <https://docs.python.org/3/library/__main__.html> (there should be
better documentation, but I didn't manage to find it...)
