RainStorm For simple operations like 5*4 using shift operator may be slow, but when the operands grow, it can still be faster. For example 2<<100 is already much faster than 2*2**100.
But actually I thought bitwise operators were absolutely faster than arithmetic operators, but it might be about Python that they always aren't.

Those bitwise operators are really slow. Don't recommend using them.

Seb TheS yeah, you are right.

Shift right operation is equivalent to integer division by 2**nb_bits. You could achieve the same result using:
1- floor division: 5 // 2
2- Int(5/2)
