I just dont understand, It says no output and that my_dog is not defined. class Pet:
def __init__(self):
self. name = ''
self. age = 0

def print_info(self):
print('Pet Information:')
print(' Name:', self. name)
print(' Age:', self. age)

class Dog(Pet):
def __init__(self):
Pet.__init__(self)
self. breed = ''

def main():
my_pet = Pet
my_dog = Dog

pet_name = input()
pet_age = int(input())
dog_name = input
dog_age = int(input())
dog_breed = input()

my_pet. name = pet_name
my_pet. age = pet_age
my_pet. print_info()

my_dog. name = dog_name
my_dog. age = dog_age
my_dog. breed = dog_breed
my_dog. print_info()

# TODO: Create generic pet (using pet_name, pet_age) and then call print_info()

# TODO: Create dog pet (using dog_name, dog_age, dog_breed) and then call print_info()

# TODO: Use my_dog. breed to output the breed of the dog
