How do I reduce dicts in Python with standard library only?

In Python, you can reduce dictionaries to a single value using the built-in `functools.reduce` function. This function applies a rolling computation to sequential pairs of values in an iterable, making it possible to combine dictionary values based on custom logic. Below is an example of how to reduce a dictionary to sum its values:

For instance, if you have a dictionary with integers as values and you want to find their total sum, you can use the following code:

from functools import reduce my_dict = {'a': 1, 'b': 2, 'c': 3, 'd': 4} total_sum = reduce(lambda x, y: x + y, my_dict.values()) print(total_sum) # Output: 10
