I have wanted do-while loops in exactly one kind of algorithms, when you generate something and you have to keep trying until it gets right. For example, generating random and non-overlapping points on a grid: import random grid = dict() for i in range(10): while True: x = random.randint(0, 4) y = random.randint(0, 4) if not (x, y) in grid: break grid[x, y] = 1 The loop runs one or more times until a vacant spot in the grid is found. This type problem would be better expressed using a do-while: import random grid = dict() for i in range(10): do: x = random.randint(0, 4) y = random.randint(0, 4) while (x, y) in grid grid[x, y] = 1 -- mvh Björn -- http://mail.python.org/mailman/listinfo/python-list
