How about "command-line interfaces"? Also, I don't know what "signature
in docstring" means? Is that something that Python programmers (not me)
would understand?

The indentation should be shifted to the right.

Do dnspython and idna need to be native-inputs? Are they only used to
build?

It's safe to disable this test?

It doesn't need to use dateutil, email-validator, and ukpostcodeparser
at run-time?

Yes, the provider provides names in (first, last) or (prefix, first,
last) forms, I think the test code is just outdated.

It need dateutil and six at runtime, and they're included in the pth
file, I can import them in python from:
  `guix environment --ad-hoc python python-fake-factory -- python3'

IIUC, I don't need to propagate dateutil and six, right?

Oh, it's needed and missing from PYTHONPATH, I should propagate it.

They're needed at runtime, and included in the pth file.
But I'm not sure whether or not inputs for python should be
native-inputs, I never cross build python modules for other
architertures.

Should I put dnspython and idna into inputs, or propagated-inputs?

If they’re used at run time, they’re not ‘native-inputs’.  (In practice
we cannot cross-compile Python stuff currently, so this is largely a
theoretical concern, but it doesn’t cost much to get it right.)

If the installed code “import”s them, then they should be propagated.

OK, done.  I'm fine with propagated them, but there are many python
packages use inputs for runtime depends and rely on the pth file too.

What's the current practice?

AIUI, what Ricardo is saying in this message is that current practice is
to propagate inputs that are needed at run time, even though that sucks
in some ways.
