If you have:

  <curdir>
    /subdir
        __main__.py

Then in 3.3+, both of the following will work:

    python3 subdir
    python3 -m subdir

They do slightly different things, though.

In the first case, "subdir" will be added to sys.path, and then python will execute the equivalent of "python3 -m __main__"

In the second case, the current directory will be added to sys.path, and python will execute the equivalent of "python3 -m subdir.__main__"

The first case is the directory execution support that was added way back in Python 2.6.

The second case is a combination of the package execution support added in Python 2.7/3.1 and the implicit namespace packages support that was added in Python 3.3.

Interesting find - the possibility of the latter situation hadn't occurred to me before :)
