Как вернуть кортеж из функции в Python?

def split(string):
    half = len(string) // 2
    first = string[:half]
    second = string[half:]
    return first, second

split('hallo') # ('ha', 'llo')
type(split('hallo')) # <class 'tuple'>

def get_values(dictionary):
    name = dictionary['name']
    age = dictionary['age']
    city = dictionary['city']
    return name, age, city

get_values({'name': 'Lana', 'age': 17, 'city': 'London'}) # ('Lana', 17, 'London')
type(get_values({'name': 'Lana', 'age': 17, 'city': 'London'})) # <class 'tuple'>
