[docs] [issue21784] __init__.py can be a directory

[Berker Peksag]

Berker Peksag added the comment:

I think this is related to PEP 420.

    $ tree pkg/
    pkg/
    ├── foobar.py

    $ python3.2 -c "from pkg import foobar"
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
    ImportError: No module named pkg

But, with Python 3.3 and newer:

    $ python3.3 -c "from pkg import foobar"
    hello

See https://docs.python.org/3/whatsnew/3.3.html#pep-420-implicit-namespace-packages for the whatsnew entry.
