Looks like it should indeed work, can you do it with comprehension expressions?

[stefpiatek]

This certainly does work, can you do them all with comprehension expressions?

So something like this

Suggested change

	ages = []
	for i in range(len(group)):
	vals = list(group.values())[i]
	ages.append(vals["age"])
	return max(ages)
	ages = [person["age"] for person in group.values()]
	return max(ages)

Also FYI, when iterating through something, it's a lot less common (and not considered pythonic) to use a range, instead you can just iterate through the items

Suggested change

	for i in range(len(group)):
	relations = list(group.values())[i]["relations"].values()
	for person in group.values()):
	relations = list(person["relations"].values())

and so on

🎉 enjoy that you'e added docstrings

[stefpiatek]

this is a great place for f strings which you can format strings with, even evaluting code inline

Suggested change

	oldest_person_age = max_age(group)
	print("The oldest person is in the group is", oldest_person_age,"years old!")
	oldest_person_age =
	print(f"The oldest person is in the group is {max_age(group)} years old!")
