Introspect Python type annotation, with ease.

Modern Python libraries often use type annotations, this library is intended to help "de/serialize" Python type hints to something you can work with.

Sample Usage:

from typingref import TypeHinter
from typing import Union


class MyType:
    ...


def foo(p: Union[int, str, float]) -> MyType:
    ...


p_type = TypeHinter.from_annotation(foo.__annotations__['p'])

if p_type.is_union():
    for t in p_type.of_type:
        ...

assert Union[int, str, float] == p_type.as_annotation()
