Usage

PyPI: https://pypi.org/project/typestr/0.1.0/

pip install typestr

from typing import Literal
from typestr import render_function, render_type


def foo(x: int | None, y: list[str]) -> bool:
	pass


print(render_function(foo))
print(render_type(
	list[
		Literal[200, 300, 400]
		| tuple[str | int, str, dict[str, int | float], ...]
		]
))

Output:

(x: int?, y: list<str>) -> bool
list<200 | 300 | 400 | (str | int, str, dict<str, int | float>, ...)>
