('%c' % 255) == chr(255) == '\xff' '%c' % 256 raise an "OverflowError: unsigned byte integer is greater than maximum" and chr(256) raise a "ValueError: chr() arg not in range(256)". I prefer the second error ;-) str.format() should follow the same behaviour. str is a byte string: it can be used to create a network packet or encode data into a byte stream. '%c' is useful for that, and str.format() should keep this nice feature.
