Python run time vs development time dict key check

development_time_check.py

from typing import TypedDict


class Movie(TypedDict):
    name: str
    year: int


def foo(movie_params: Movie):
    pass  # do your thing


foo({'name': 'John Doe', 'year': 1337})  # all good during development time


foo({'name': 'John Doe', 'yar': 1337})  # Expected type 'Movie', got 'dict[str, Union[str, int]]' instead 

run_time_check.py

from typing import Dict, Any


def foo(movie_params: Dict[str, Any]):
    allowed_movie_keys = {'name', 'year'}
    if not allowed_movie_keys >= movie_params.keys():
        print('Runtime Error!')
    else:
        print('Success!')

        
foo({'name': 'John Doe', 'year': 1337})
# Success!


foo({'name': 'John Doe', 'yar': 1337})  # typo in year
# Runtime Error!
