Inspect params and return types

Question

Is it possible using Python 3 syntax for declaring input parameters and return value types determine those types? Similarly to determining the number of parameters of a func

Answer 1

inspect can be used:

>>> def foo(name: str) -> int:
...     return 0
>>> 
>>> import inspect
>>> 
>>> sig = inspect.signature(foo)
>>> [p.annotation for p in sig.parameters.values()]
[]
>>> sig.return_annotation

@vaultah's method looks even more convenient, though.
