Dealing with nested mixed types

Previously, we used the in expression so see if data is in a dictionary such as if 'cookies' in recipes_dict. However, what if we want to find data in a dictionary key that is a list of dictionaries? In that scenario, we can use a for loop to loop over the items in the nested list and operate on them. Additionally, we can leverage list comprehensions to effectively filter nested lists of dictionaries. For example: [cookie for cookie in recipes["cookies"] if "chocolate chip" in cookie["name"]] would return a list of cookies in recipes list that have chocolate chip in the name key of the cookie.

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

  • Use a for loop to iterate over the squirrels found in the Tompkins Square Park key of squirrels_by_park:
    • Safely print each activities of each squirrel.
  • Print the list of 'Cinnamon' primary_fur_color squirrels found in Union Square Park using a list comprehension.
