I got stuck at first trying to loop through the list of dictionaries to find specific information, since I it has been a while I have had accessing values inside nested structures. I got un-stuck by reviewing examples of how to use keys in dictionaries and by printing out parts of the data step by step to see how it was organized.

# Each of the functions below expects a list of dictionaries as its first

# argument. Two examples of the expected input are provided in people.family

# and people.friends.

|
# Your job is to complete these functions. Remove the NotImplementedError from
|

# each and instead write code which returns the expected values.
