"Modules" section in the tutorial says that
"The files are required to make Python treat directories containing the file as packages. "

But, thanks to PEP 420, is not required after Python 3.3.

In my experience, beginners have enough trouble getting packages right without complicating the tutorial with a rarely-used advanced feature like namespace packages.

I don't think this needs more than perhaps a footnote, if that.

I agree that implicit namespace packages don't deserve more than a footnote in that page.

However, since I often have to answer questions about packages, I'm thinking that perhaps it would be better to expand that page and maybe have a page dedicated to modules and one to packages, where PEP 420 and other common issues could be covered in more details.

I think it is just a noise for the tutorial readers.

I created a post about misunderstanding of PEP 420.

How about adding note in top of the PEP 420 instead?

.. note::
   Namespace packages are not regular packages.  It
   is a feature for very special use case.
   Don't omit ```` in regular packages.
