Take the function below (signature only), where the parameters a and b should be a string and an integer, respectively, and with a string return type. What is the proper way to document these requirements using type hints? def func(a, b): code example

Example 1: python function argument type

def pick(l: list, index: int) -> int:
    return l[index]

Example 2: python type hint list

# For collections, the name of the type is capitalized, and the
# name of the type inside the collection is in brackets
x: List[int] = [1]
x: Set[int] = {6, 7}
  
# For simple built-in types, just use the name of the type
x: int = 1
x: float = 1.0
x: bool = True
x: str = "test"
x: bytes = b"test"
