WebSep 28, 2024 · The >> operator does a binary bitshift. It moves the binary representation of 1234 on place to the right, discarding the rightmost (least significant) bit. Therefore you code does not result in 3412. You probably want string rotation instead: >>> def rotr (string, n): ... return string [n:] + string [:n] ... >>> rotr ("1234", 2) '3412' WebThe bits are whole 1 or 0 - you can't shift by a part of a bit thus if the number you're multiplying by is does not factor a whole value of N ie. since: 17 = 16 + 1 thus: 17 = 2^4 + 1 therefore: x * 17 = (x * 16) + x in other words 17 x's thus to multiply by 17 you have to do a 4 bit shift to the left, and then add the original number again:
