I prefer print("A {0} can be very cute!".format(pet)) .format() is very versatile. d = {'first': 'Robert', 'last': 'Paulson'} print("His name was {first} {last}!".format(**d)) >> His name was Robert Paulson! class Person: def __init__(self, first, last): self.first, self.last = first, last p = Person('Robert', 'Paulson') print("His name is {0.first} {0.last}!".format(p)) >> His name was Robert Paulson! You also do not need to know what type is being passed in as the __str__ method is used for .format().
