Help with while loop creating an infinite loop.

[FWendeburg]

Hi, i have a problem with this python code that should not create an infinite loop. This code should take one item from one list, print a message using that item and then add it to another list.At the end of the program all the items in the second list should be printed.

sandwich_orders = ['halumi', 'tuna', 'ham and cheese', 'salami', ]

finished_sanwiches = []

while sandwich_orders:
    sandwich_ordered = sandwich_orders.pop()
    print("\nMaking your " + sandwich_ordered.title() + " sandwich.")
    sandwich_orders.append(sandwich_ordered)

print("\n===This sandwiches have been finished making.===")
for sandwich in finished_sanwiches:
    print(sandwich.title())

What the program does:

Error:
Making your Salami sandwich.

Making your Salami sandwich.

Making your Salami sandwich.

Making your Salami sandwich.

Making your Salami sandwich.

Making your Salami sandwich.

Making your Salami sandwich.

-this continues to infinity-

Use a for instead. Note that you append the "pop" in the last statement.

for sandwich_ordered in sandwich_orders:
    print("\nMaking your " + sandwich_ordered.title() + " sandwich.")

while sandwich_orders:
    sandwich_ordered = sandwich_orders.pop()
    sandwich_orders.append(sandwich_ordered)

I think you meant to append that to the finished_sanwiches list.

Thanks for your help :D.
