Return Types
Return types of the function are shown through the use of the
-> operator1
def test() -> int = return 3

If no return type is explicitly described, the
null type is assumed to be the return type. The null type is returned from a function in 3 cases: 1. When there's no return statement in the function. 2. When there's an empty return statement in the function. 3. When null is explicitly returned from the function.Last modified 2yr ago
