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

My favorite is "be concise."have you ever received an email and had to read a page full of information? by the time you finished reading it, you had to re-read it? i have even hit "reply" so that i could break it down into separate paragraphs and send it back to myself.what is concise? get to the point, fast. when opening an email like this, some will close it or print it to read later.i learned to use the subject line to prepare the reader for content. such as, "need on (blank), " "info only re: (blank)," "request input on (blank)," "read before (blank) meeting." these are just some.if you are asking for something, make that your first sentence. follow this by who, what, when, where, and how. use these, as necessary. example; (1) who (who needs it and or who does it), (2) what (specific description of what is needed), (3) when (specific, i need this by 8: 00 am monday or i need this by 10: 00 am today), (4) where (does it have to be printed and taken to someone, maybe the place of the meeting), (5) how (i need it scanned or faxed back to me at this email address, provide me with a hard copy).do not send yet. re-read it. did some spell check change a word? maybe let someone else read it for understanding. you want to avoid multiple emails asking for clarification. if important, put a read receipt on it. you will know it was opened, not necessarily read.end with a you.
