A very nitpicky nitpick: this comment should be spelled as "is true" (lowercase), rather than "is True" since the requirement is that predicate's "truth value" is true, rather than predicate *is* the boolean "True" singleton; e.g. if someone passes in an int as predicate, its nonzero-ness would be used, rather than always being false (since no int *is* the boolean singleton "True"). > + > + :param bool predicate: Whether the test should pass. > + :param str message: Message to emit. > + """ > + if predicate: > + print_pass(message) > + else: > + print_fail(message)
