As far as I understand, assuming dir/ contains a __main__.py file
$ python dir
is equivalent to
$ python dir/__main__.py
in that it's behaviourally nothing more than executing a script in that dir and setting sys.path accordingly. This is the same in Python 2 and Python 3.
This, together with the notion that zip files and directories are treated in the same way, allows running
python file.zip
since we have no option for executing a file *within* the zip file.
Altogether, this is a significantly different behaviour than the one for "python -m pkg". That would be closer to:
>>> import pkg.__main__
This also explains why the package __init__ is executed first (you import the package first, then the module). A significant difference is that it's not a real import (just as pkg.__init__ is not imported) and sys.modules is not affected. |
