To apply a function to the values of an entire dictionary in Python, you can use a loop and the .values() method.

In Python, you can apply a function to the values of an entire dictionary by using a loop and the .values() method.

The syntax is: {key: function(value) for key, value in dictionary.items()}. This applies the function to every value in the dictionary.

Here's an example:

my_dict = { 'a': 1, 'b': 2, 'c': 3 }

for key in my_dict:
my_dict[key] = my_function(my_dict[key])

This code will loop through each key in the dictionary and apply the my_function() to its corresponding value, modifying the dictionary in-place.
