Is while True: a suitable way to repeat a block until an accepted case is reached?

Question

Is while True an accepted method for looping over a block of code until an accepted case is reached as below? Is there a more elegant way to do this?

while True:
    value = input()
    if value == condition:
        break
    else:
        pass
# Continue code here.

Thank you for any input.

Answer 1

That's the way to do this in Python. You don't need the else: pass bit though.

Note, that in python 2.x you're likely to want raw_input rather than input.

Answer 2

If it's deterministic, then yes. If it is not deterministic (thus meaning you could be stuck in a loop forever at some statistical likelihood) then no.

If you wanted to make it a little more clean and easier to debug as the code grows larger, use a boolean or integer to indicate the status of your loop condition.
