Help with loop & user input

[rdDrp]

hey thanks for reply........
I am from finance background, regardless

I am learning coding as hobby.
So you guys are my teachers in someway. So, yes we all can agree as this being homework.
now assuming that this is homework, can any one give me idea as how to proceed??

do i need a list or dictionary or variable & or define a function?

What i had done?

print('How many cars do you have? ')
user_input = input()

if user_input == int:
    pass
else:
    print('Please input number only. ')

def hmCars(howManyCars):
    for x in user_input:
        if user_input <= 0:
            break
        else:
            for x in user_input

how i can loop through user_input ?

ok '0' is not an integer. So i don't need the break statement.
