Python | Check if given multiple keys exist in a dictionary

A dictionary in Python consists of a collection of key-value pairs. Each key-value pair maps the key to its associated value.

Input : dict[] = {“geeksforgeeks” : 1, “practice” : 2, “contribute” :3}
keys[] = {“geeksforgeeks”, “practice”}
Output : Yes

Input : dict[] = {“geeksforgeeks” : 1, “practice” : 2, “contribute” :3}
keys[] = {“geeksforgeeks”, “ide”}
Output : No

Let’s discuss various ways of checking multiple keys in a dictionary :

Method #1 Using comparison operator :
This is the common method where we make a set which contains keys that use to compare and using comparison operator we check if that key present in our dictionary or not.

True
False

Method #2 Using issubset() :
In this method, we will check the keys that we have to compare is subset() of keys in our dictionary or not.

True
False

Method #3 Using if and all statement :
In this method we will check that if all the key elements that we want to compare are present in our dictionary or not .

keys are present
keys are not present
