The dictionary contains the elements with key and their associated value. Example. The indexOf() method will help you to check if an element exists in the array by returning the position of the index of the first element that match. The in operator checks if the list contains a specific item or not. We can try getting a key, and if the returned value is None, that means it's not present in the dictionary: Python list is an essential container as it stores elements of all the data types as a collection. Check if a Value Exists in a Python Dictionary Using .values () Similar to the Python dictionary .keys () method, dictionaries have a corresponding .values () method, which returns In Naive method, one easily uses a loop that iterates through all the elements to check the existence of the target element.
