How to Compare Two Dictionaries in Python

by Abdul Rawoof A R Updated: Jan 31, 2023

Guide Kit

In Python, you may loop through a dictionary's key-value pairs using the "items()" function, and then use the "in" operator to see if the key is present in the other dictionary. You may compare the values if it's there. You can include it in a list of differences if it is absent.

items(): The items() method in Python is used to retrieve a view object that contains a list of dictionaries (key, value) tuple pairs. The view object can be iterated over to access the key-value pairs of the dictionary. This is useful when you want to loop through the key-value pairs of a dictionary and perform some operation on each of them. It is also useful when you want to create a copy of a dictionary and keep it updated with the original dictionary.
in operator: The in operator in Python is used to check whether a value is present in a container data type such as a list, tuple, set, or dictionary. It returns True if the value is found in the container and False otherwise. It is a very useful operator when you want to check if a value is present in a container data type. It saves time and lines of code.

For more information about comparing two dictionaries with more values in one in Python, refer to the code below.

for key, value in result.items():
    if value != result2.get(key, 0):  #You can add additional condition to check if key present in `result2`
        print("%s not equal"% (key))

jazi not equal
juge not equal
juha not equal
