Bitwise Rotate Right

Question

I am trying to convert this C function into Python;

typedef unsigned long var;
    /* Bit rotate rightwards */
    var ror(var v,unsigned int bits) {
        ret

i know its nearly 6 years old

I always find it easier to use string slices than bitwise operations.

def rotate_left(x, n):
    return int(f"{x:032b}"[n:] + f"{x:032b}"[:n], 2)

def rotate_right(x, n):
    return int(f"{x:032b}"[-n:] + f"{x:032b}"[:-n], 2)
