Thanks for your solution - can you do it using a comprehension expression?
So using the example solution for the first part it would be:

print(max(person["age"] for person in group.values()))  
# 34

nice, you could also make a function that calculates the mean from a list and use that on the output of the list

def mean(data):
    """Compute the average of a non-empty list of numbers."""
    return sum(data) / len(data)

mean([len(person["relations"]) for person in group.values()])  # 1.5
