Just applying these on numbers is already implemented: In [17]: bin(14) Out[17]: 0b1110
In [18]: bin(14 << 1) Out[18]: 0b11100 In [19]: 14 << 1 Out[19]: 28 It might be useful to define these things symbolically, so that you could say x << y, and it would give you a symbolic result (and stuff like x & 0 would simplify to 0). By the way, except for shifts, you can pretty much just use regular logic and assume that the expression is repeated eight times per byte.
