The original question was closer to the related issue of "indicate return types
for all built-ins," conversation log follows (UTC-5):
```
09:33:50 ringo__ | is there a stdlib api docs which actually has *full*
functions signature?
09:34:27 ringo__ | for example,
https://docs.python.org/3/library/functions.html, function
| abs(x), it returns what, int? I need to read the
whole sentence to figure
| out the return value of a function?
09:34:48 ringo__ | (or argument for that matter)
09:35:51 bjs | ringo__: well like it says it doesn't just support
int
09:36:00 bjs | int, float, or any type that supports it
09:37:01 bjs | in general you can find actual type annotations for
the functions in the
| typeshed
|
https://github.com/python/typeshed/blob/master/stdlib/builtins.pyi
09:37:32 bjs | I wonder if it would be useful to include the
typeshed annotation in the
| docs, or whether it would be more confusing
09:37:49 ringo__ | Thanks bjs ! I'll bookmark this typeshed
09:38:13 SnoopJ | abs() will do whatever __abs__() on the type does,
which can be different
| for any given type. You'd expect T -> T but it's not
guaranteed.
09:38:18 ringo__ | I used abs() as an example. In fact I was wondering
what does print()
| return. I *guessed* it returns None, but the docs
won't say
09:39:05 ringo__ | I could do a try-it-yourself approach but I was
puzzled why the docs
| simply won't give you full fn signature, ie
print(..) -> None
09:39:17 SnoopJ | that one is just an omission :)
