Python: store userinput in list until quit

This is my current code:

    account_number = [" "]
uinput = int(input("Type some Bank account numbers. Type "quit" to stop: "))
while uinput != "quit":
    account_number.append(uinput)
else:
    print(Kontonummern, frozenset)

I want to store "uinput" in my list "account_number" until the user enters "quit". After that the list should turn into a frozenset and print it out.

As of now I can only type 1 account number and then the programm crashes.

Try this:

account_number = [" "]
uinput = input("Type some Bank account numbers. Type quit to stop: ")
while uinput != "quit":
    account_number.append(int(uinput))
    uinput = input("Type some Bank account numbers. Type quit to stop: ")
else:
    print(Kontonummern, frozenset(account_number))

The problem was that you were never updating your uinput. And your input can be "quit" but you cast it to an int, which was also causing problems.
