How to print only once the items in a list (Python 2.7)

Question

I'm a beginner at Python and I've made a code that prints a list of products that the user entered, but whenever I print it, it doesn't break when it reaches the last element...
EDIT: The string is supposed to be with no spaces. ex: Cottage,Cheese,Bacon
Here's my code:

def menu():
    print "1. View products"
def view(products):
    print products
def main():
    str1 = raw_input("")
    products =str1.split(',')
    menu()
    choice = input("")
    while (choice != 0):
        if(choice == 1):
            view(products)
main()

Answer 1

You've got an infinite loop which is why the list keeps getting printed. You need to ask for input more than once otherwise the loop will never end

choice = None
while (choice != 0) and (choice != 1):
    if(choice == 1):
        view(products)
    choice = input("Type 1 to view products, 0 to quit: ")

Answer 2

In this code you only prints list, and while in this case generates infinite loop. In your example products is a list. So why you wouldn't pass it to view function, and then pass it to for loop to print content of products
