What do you use to iterate over a dictionary's keys and values?

When working with a dictionary in Python and you want to iterate over both its keys and values simultaneously, the method to use is dictionary.items(). This method returns a view object that displays a list of a dictionary's key-value tuple pairs, making it easy to loop through both elements in a single iteration.

For example, when you use a for loop with dictionary.items(), you can unpack these tuples directly into key and value variables, allowing you to process each key-value pair efficiently.

Using dictionary.keys() would only allow you to iterate over the keys of the dictionary, while dictionary.values() would only provide access to the values. Neither of these methods would let you access both keys and values concurrently, which is necessary for many tasks that involve dictionary data structures. The option dictionary.loop() does not exist in Python and is not a valid way to iterate over dictionary contents.
