In the above program, we delete thekey:valuepairs ofmarriedfrom internal dictionary3and4. Then, we print thepeople[3]andpeople[4]to confirm changes. Example 6: How to delete dictionary from a nested dictionary?
As we can see, only the items with even value have been added, because of theifclause in the dictionary comprehension. To learn more about if clause, visitPython if...else. Example 5: Multiple if Conditional Dictionary Comprehension original_dict = {'jack':38,'michael':48,'guido':57,'j...
In this example, we will take an empty dictionary, add key:value pairs to it one by one. As a result, we will know the order in which the items are added to the dictionary. Then, we shall call popitem() and observe the order of items that will be removed. Python Program </> Cop...
Example:Original dictionary: {'Indore': 2, 'Delhi' : 5, 'Mumbai' : 1, 'Manali' : 3, 'Patna': 8} Shuffled dictionary: {'Indore': 1, 'Delhi' : 8, 'Mumbai' : 5, 'Manali' : 2, 'Patna': 3} To randomize the dictionary values, we will first convert the dictionary to a list...

To determine the length of a dictionary in Python, you can use the built-inlen()function. This function takes the dictionary as an argument and returns the number of key-value pairs it contains. For example, if you have a dictionarystate_population = {"California": 39538223, "Texas": 291...
