It looks to me like you'd be better off reading each input number into a list.
You may also find it useful to write a generator function to read your values in:
>>> def read_numbers():
... while True:
... number = int(raw_input('Enter a number: '))
... if number == 0:
... break
... yield number
...>>> read_numbers() <generator object at 0x0114CE18>
>>> for number in read_numbers(): ... print number ... <... after typing 5 ...> 5 <... after typing 6 ...> 6 <... after typing 9 ...> 9 <... after typing 0 ...> >>>
>>> list(read_numbers()) <... after typing 2, 4, 5, 5, 8, 0 ...> [2, 4, 5, 5, 8]
The read_numbers function creates a generator object which will query the user for a number until it sees the number 0. Because you get a generator object from this function, you can easily convert it to a list if you need to, or iterate on it directly.
Also note that I use int(raw_input(...)) instead of input(...). It's a few more keystrokes, but it's probably a good habit to get into -- input(...) has some security holes.
