New submission from YoSTEALTH:
Type Hints Syntax
-----------------
Goal: Is to make it easy to read function/methods arguments, yet keep the new
and cool Type Hints.
For example this is a code from one of my function. Its getting to that point
of what the heck is going on here?
def find_replace(string: str, find: (str, dict, list, tuple, set), replace:
(str, list, tuple, set)='') -> str:
pass
I know it can be rewritten as:
T = (str, dict, list, tuple, set)
def find_replace(string: str, find: T, replace: T='') -> str:
pass
But when you start using variable to represent another variables type... maybe
we are losing the plot here!
What if we could have both? Readability and type reference, what if it could be
written as:
def find_replace(string, find, replace):
targ str, *(str, dict, list, tuple, set) -> str
# code here ...
targ = type argument (like *args and **kwargs)
Calling a "targ" like we call "global" but to represent types.
Simple Examples:
def Redirect(url='', code=301):
targ (str, int) -> None
Just think about it...
