Wrong type warning when working with dictionary

Answered

Consider this very simple python example:

def b():
"""
:rtype: dict[str, int]
"""
return {"b": 1}

a = b()

a["test"] = "test"

 

 

The last line gives me this error

Expected type 'int' (matched generic type '_VT'), got 'str' instead

which is not correct in my opinion. Is there any workaround for this. I don't like to specify ` :rtype: dict[str, int | str]` in function because it is incorrect.
