It would help if you showed us the code you wrote with the loop.
Its difficult to guess what you did wrong when we can't see it.

Here is a hint...
You could collect the prices in a list then use sum()
to get the total. Then your loop only needs to read a
value and append() it to the list. break out of the loop
if the user enters 0, or -1, or whatever you want to stop it.

Notice one print uses parentheses, the other doesn't.
Which version of Python are you using? Its better if
you stick to one form or the other as appropriate
to your Python version.
