[New-bugs-announce] [issue46312] range() function could accept slice() objects as parameters

[yota moteuchi]

New submission from yota moteuchi <yota.news at gmail.com>:

This improvement proposal is close to : https://bugs.python.org/issue42956 and also detailed in https://stackoverflow.com/questions/13855288/turn-slice-into-range

to iterate over a slice, the recommended method seems to be : 

s = slice(5,100,3)
for i in range(s.stop)[s] :
    # do something

but if range() accepted directly a slice, it would dramatically improve the readability :

s = slice(5,100,3)
for i in range(s) :
    # do something

and it could be convenient, especially inside the __getitem__ property. I'll try to make a quick patch to test...
