Python: How to keep repeating a program until a specific input is obtained?

for-loop, loops, python, while-loop

Solution

There are two ways to do this. First is like this:

while True:             # Loop continuously
    inp = raw_input()   # Get the input
    if inp == "":       # If it is a blank line...
        break           # ...break the loop

The second is like this:

inp = raw_input()       # Get the input
while inp != "":        # Loop until it is a blank line
    inp = raw_input()   # Get the input again

Note that if you are on Python 3.x, you will need to replace `raw_input` with `input`.

Problem

I have a function that evaluates input, and I need to keep asking for their input and evaluating it until they enter a blank line. How can I set that up? ``` while input != '': evaluate input ``` I thought of using something like that, but it didn't exactly work. Any help?
