PEP 561 uses "py" namespace

[Florian Bruhin]

So I just read PEP 561 and noticed it uses package data for the py.typed package (plus apparently such a file in the package?) for type stubs.

Is that going to be an issue? Would it make sense to try and convince the authors to not use py.typed as name for that marker?

[Ronny Pfannschmidt]

based on a initial skim, this is a in package package data filename, so i don't see any issues

[Anthony Sottile]

This is just a data file and not actually a namespace.

For example, if I wanted to indicate that mymod is typed I'd have a structure like:

mymod/
├── __init__.py
├── foo.py
└── py.typed

And then I'd include the py.typed file as part of the package_data in setup.py
