[New-bugs-announce] [issue27989] incomplete signature with help function using typing

[David E. Franco G.]

New submission from David E. Franco G.:

the issue is that when calling help on a function annotated with typing, all the relevant information is lost, for example

from typing import List, Any, Iterator, Tuple

def foo(data:List[Any]) -> Iterator[ Tuple[int,Any] ]:
    ...
 
when calling help on that

>>> help(foo)
Help on function foo in module __main__:

foo(data:typing.List) -> typing.Iterator

>>> 

all the information is lost, the output should look like this

>>> help(foo)
Help on function foo in module __main__:

foo(data:List[Any]) -> Iterator[ Tuple[int, Any] ]:

>>> 

where all the information that I put in the annotation is preserved and the typing.* are eliminated since they only add unnecessary noise

while reporting this issue in the typing module (https://github.com/python/typing/issues/279) I was told that is a bug with the inspect module and that help may need modification.

Thank for your time.
