Checking dictionaries for data

You can check to see if a key exists in a dictionary by using the in expression.

For example, you can check to see if 'cookies' is a key in the recipes dictionary by using if 'cookies' in recipes: this allows you to safely react to data being present in the dictionary.

We've loaded a squirrels_by_park dictionary with park names for the keys and a list of dictionaries of the squirrels.
