Incorrect. bools *are* ints in Python, beyond any doubt. >>> isinstance(True, int) True True and False are instances of int. That's all you need to know. > But "str(True)" is "True". I assume that you're not comparing the literal strings "str(True)" and "True" (which would make your claim incorrect). Nevertheless, leaving out the quotes is also incorrect: >>> str(True) is True False The only way to get your claim to work is to mix'n'match quotation marks, leaving one pair in and dropping the other: >>> str(True) is "True" True But so what? What do you think that proves? All it shows is an implementation detail to do with caching of certain small strings: >>> str(5) is "5" True -- Steven -- http://mail.python.org/mailman/listinfo/python-list
