How do I reduce dicts in Python with type hints?

In Python, you can reduce dictionaries using various methods, including dictionary comprehensions and the built-in `functools.reduce` function. Below is an example demonstrating how to reduce a dictionary with type hints.

This example shows how to combine the values of a dictionary using the `functools.reduce` method, with type hints for clarity.

from functools import reduce from typing import Dict, Any def reduce_dict(d: Dict[str, int]) -> int: return reduce(lambda x, y: x + y, d.values()) example_dict: Dict[str, int] = { 'a': 1, 'b': 2, 'c': 3 } result = reduce_dict(example_dict) print(f'The reduced value is: {result}') # Output: The reduced value is: 6
