Bitwise operations of Python

The right shift is the inverse of the left shift, that is, the relative binary number moves to the right, one unit to the right is the equivalent of dividing by 2, the right shift of two units is equivalent to dividing by 4, the right shift of 3 units is equal to dividing by 8, the right shift n units is equivalent to dividing by 2 n power ""
