How to Use Type Hints for Multiple Return Types in Python, The first parameter is a list of arguments that the input function takes In this case func expects only one argument of type string The second parameter of the Callable type hint is the return type which in this case is a tuple of two strings
PEP 484 Type Hints peps python
Get type hints a utility function to retrieve the type hints from a function or method Given a function or method object it returns a dict with the same format as annotations but evaluating forward references which are given as string literals as expressions in the context of the original function or method definition
PEP 483 The Theory of Type Hints peps python, There are several ways to define a particular type By explicitly listing all values E g True and False form the type bool By specifying functions which can be used with variables of a type E g all objects that have a len method form the type Sized

12 Beginner Concepts About Type Hints To Improve Your Python Code | by Ahmed Besbes | Towards Data Science
Type hints introduced in Python 3 5 as a part of the standard library via PEP 484 allow you to specify the expected type of a variable function parameter or return value Why use type hints While dynamic typing offers flexibility it also creates room for potential bugs Here s where type hints come in Type Hinting in Python Dagster Blog. 1 Introduction Using type hints in programming refers to providing hints or annotations in your code that specify the expected data types of variables function parameters and return values These type hints don t affect the actual runtime behavior of your code but serve as documentation for both developers and tools 00 24 But instead of doing so in your docstrings you ll use Python type hints to declare the argument and return types of your functions First you import Union from the built in typing module which allows you to specify multiple types for an argument
