In the above example, I have used a nested dictionary to store guest records in a hotel. Now I can retrieve the name of the guests staying in the hotel rooms and the ID they presented at the time of check-in. In addition, nested dictionaries are easier to traverse and contain much rea...

The .values() method lets you traverse the values in the target dictionary. In this example, you iterate over team names one by one. Note that when you use the .values() method, you can’t access the dictionary keys.Finally, iterating over both keys and values in a Python dictionary ...
