[Python] Typehints for dicts in Python including the default values [duplicate]

I have a function that calls a bunch of other functions like this:

import inspect
def get_default_args(func):
# obtained from: https://stackoverflow.com/questions/12627118/get-a-function-arguments-default-value
signature = inspect.signature(func)
return {
k: v.default
for k, v in signature.parameters.items()
if v.default is not inspect.Parameter.empty
}

def func_a(self, var_a:int=10, var_b:str = 'a') -> float:
pass

def func_b(self, var_c:int=10, var_d:str = 'b') -> float:
pass

def main_func(args_a, args_b):
value_a = func_a(**args_a)
value_b = func_b(**args_b)

# Get the options and default values to call the functions
args_a = get_default_args(func_a)
args_b = get_default_args(func_a)

# Edit the default values
args_a = {"var_b":'d'}
args_b = {"var_c":5}

# Make the call to the main function
main_func(args_a, args_b)


This works, however, when I edit what is the input to func_a I would like to get all options that this functions have in the IDE similar to when I call the function func_a:

Since get_default_args is executed at runtime the IDE (like VSCode) does not recognize what options and what default values there is in args_a. For examle:



I've tried with dataclasses and TypeDicts but I have not managed to get the behavior that I'm looking for.
