WebYou can use << to multiply and >> to divide numbers in python when I time them I find using the binary shift way of doing it is 10x faster than dividing or multiplying the regular way. Why is using << and >> a lot faster than * and /? What are the behind the scene processes going on to make * and / so slow? operators bitwise-operators Share WebThe Python bitwise right-shift operator x >> n shifts the binary representation of integer x by n positions to the right. It inserts a 0 bit on the left and removes the right-most bit. For example, if you right-shift the binary representation 0101 by one position, you’d obtain 0010.
