Quite simple really, and yes you are right. Use a while loop: >>> from random import seed, random >>> from time import time >>> seed(time()) >>> def foo(): ... if 0.5 < random() < 0.6: ... return True ... >>> x = foo() >>> while x is None: ... x = foo() ... >>> x True >>> cheers James -- -- James Mills -- -- "Problems are solved by method" _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
