How do I map sets in Python with type hints?

In Python, you can use type hints to indicate the expected types of elements in a set. This can help improve code readability and provide better insights for tools like linters and IDEs. Below is an example of how to map sets with type hints in Python.


from typing import Set

def process_numbers(numbers: Set[int]) -> Set[int]:
    """Squares each number in the given set."""
    return {number ** 2 for number in numbers}

# Example usage
numbers_set: Set[int] = {1, 2, 3, 4}
squared_numbers: Set[int] = process_numbers(numbers_set)
print(squared_numbers)  # Output: {16, 1, 4, 9}
