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         


        

Answer 1

The shortest way I've found in Python: (note this works only with integers as inputs)

def ror(n,rotations,width):
    return (2**width-1)&(n>>rotations|n<<(width-rotations))
