Exercise

Powerful Ordered popping

Where OrderedDicts really shine is when you need to access the data in the dictionary in the order you added it. OrderedDict has a .popitem() method that will return items in reverse of which they were inserted. You can also pass .popitem() the last=False keyword argument and go through the items in the order of how they were added.

Here, you'll use the ridership_date OrderedDict you created in the previous exercise.
