TypedDict when keys have invalid names

Question

If I have a key in a dictionary with an invalid identifier, such as A(2). How can I create a TypedDict with this field?

E.g

from typing import TypedDict

class RandomAlphabet(TypedDict):
    A(2): str

is not valid Python code, resulting in the error:

SyntaxError: illegal target for annotation

The same problem is with reserved keywords:

class RandomAlphabet(TypedDict):
    return: str

throws:

SyntaxError: invalid syntax

Answer 1

This is fairly messy, but it works if you need inheritance.

class RandomAlphabet(
    TypedDict(
        "RandomAlphabet",
        {"A(2)": str, "return": str},
    ),
    SomeInheritedTypedDict,
):
    pass

You can also replace pass with other normal properties that don't use invalid identifiers or reserved keywords if you have any.
