Storing Multiple User inputs while using a loop

Question

My intent here this to query the user for multiple inputs using a loop that stops when the user inputs and integer of zero. I need to be able to recall the data in a later line of code. With that in mind I'm trying to create a list of the users input.

Python 3 code

i = False
val1 = []
while i == False:
    if  val1 != 0:
        val1 = eval(input("Enter an integer, the value ends if it is 0: "))
    else:
        i = True
        print(val1)

Under if val1 != 0: you should not assign, but .append to a list. Like this: val1.append(eval...) — soupault

it will allow me to append the list however, I still run into the problem of it not breaking out of the loop by running the else. Is there a solution to check to see if the list contains a 0 in to break out? Essentially I want to call the min and max out of the list at the very end. — Andrew Bodin

I think it would be cleaner if you use a infinite loop and break if the input is 0. Otherwise, simply append to the the list.

values = []
while True:
    val = int(input("Enter an integer, the value ends if it is 0: "))
    if val == 0:
        break
    values.append(val)

I think you need to wrap the input call in a call to int, otherwise val == 0 will never be true.

input(prompt) is equivalent to eval(raw_input(prompt)), so it should work

This solution partially works, however it doesn't seem to break out after entering a 0 value. If you run it it asks me for another input from the user. We need the int value of 0 to break out of the loop.

It works as intended for python2, but yeah, you need to convert to int for python3
