I have seen some people prefer to create a list of strings by using thing = list[str]()
instead of thing: list[str] = []
. I think it looks kinda weird, but maybe that’s just because I have never seen that syntax before. Does that have any downsides?
It is also possible to use this for dicts: thing = dict[str, SomeClass]()
. Looks equally weird to me. Is that widely used? Would you use it? Would you point it out in a code review?
With the
dump
function:from ast import dump, parse st = parse("thing = list[str]()") print(dump(st, indent=4)) st = parse("thing: list[str] = []") print(dump(st, indent=4))
