Module 2 Required Coding Activity

[silverdog]

Hi,
My code seems running fine on jupyter notebook,
but when pasted into the Module 2 Required Code Submission gived me error ...
Any hint ?

# [] create list-o-matic
# [] copy and paste in edX assignment page

zoo = ['cat', 'goat', 'cat']

def list_o_matic(animal):
    if animal == "":
        animal = zoo.pop()
        print(animal + " popped from list")
    elif animal in zoo:
        zoo.remove(animal)
        print("1 instance of " + animal + " removed from list")
    else:
        zoo.append(animal)
        print("1 instance of " + animal + " appended from list")

while True:
    if zoo == "":
        break
    else:
        animal_name = input("enter the name of an animal: ")
        if animal_name.lower().startswith("q"):
            break
        else:
            list_o_matic(animal_name)
            print(zoo)

print("goodbye")

gaved me error when submitted

Ok but what was the error?

The only thing that sticks out to me, is input(). If whatever you're submitting to is using python2, that would probably not work right. But without knowing what errors you're getting, I'm just guessing.
