Hm, there is no builtin bits type in python, but you can do something like >>> bin(int.from_bytes(b"hello world", byteorder="big")).strip('0b') The integers are first converted into binary and then operations are performed on bit by bit, hence the name bitwise operators. My input is More to the point, what makes you think this will be a bottleneck in any code you'll ever write?
