How to write a static python getitem method?

Question

What do I need to change to make this work?

class A:
    @staticmethod
    def __getitem__(val):
        return \"It works\"

print A[0]

No

Answer 1

Python 3.7 introduced __class_getitem__.

class A:
    def __class_getitem__(cls, key):
        return "It works"

print(A[0])
