The benefit of this arrangement is twofold: 1.The method returns 0 in case both dictionaries are identical, 1 if dict1 is greater than dict2, and -1 if dict1 is lesser than dict2. The collection module provides the counter(), which compare the list efficiently. We can iterate through dictionary keys one by one using a for loop. Pythons cmp () method is implemented to compare the values and keys of two dictionaries. Last updated on In this article you can see how to compare two dictionaries in python: if their keys match the difference in the keys the difference in the values The first check is to verify that two dictionaries have equal keys.
