Map: dict[str, object] = {
"image" : Image.generate,
"video" : Video.generate,

}

Here, generate(json) is a function in both cases. However I’m getting a typehint error that "object" not callablemypy(error). What should be the appropriate type instead of object for the Map?

Solution

You can use dict[str,Callable] to allow any callable object as a value, but you might want to be more specific. At the very least, it sounds like the function must return a single string (the resulting JSON value), so you can write

dict[str, Callable[[...], str]]

to allow functions that take arbitrary arguments and return a str. If you know more about what the function can accept, you can replace ... with one or more specific argument types.
