[python] Repeat-until or equivalent loop in Python

I am a beginner in Python programming. I am trying to work on this algorithm that finds convex hull using Graham's scan method. However, in the pseudocode, there is a repeat ... until loop, which I could not figure out a way to write it in Python.

How do I write a repeat ... until loop in Python?

This question is related to python loops

The answer is


REPEAT
    ...
UNTIL cond

Is equivalent to

while True:
    ...
    if cond:
        break
