[New-bugs-announce] [issue25374] Deficiencies in type hint usage in Python standard libraries

[John Michael Lafayette]

New submission from John Michael Lafayette:

I love the new type hint feature in Jetbrains IDE (PEP 0484). Now when my user defined methods return a value, I can press (Crtl+space) and see the type of that value and all its methods. Also, when I pass the wrong type in, I get a warning. 

Oddly, this does not happen with Python standard library functions. I can't get the auto-complete on objects returned by the Python standard library. The Python standard library doesn't warn me in advance if I put the wrong type in a method. How does that make sense? Please support PEP 0484 by using it in the Python standard library where appropriate.
