For example, 0b00000001. Shifting it >> 1 in C it seems to add on zero to the left and the 1 to the right gets throwned away. But doing it in python just adds one more bit, from the left. That is, 0b00000001 >> 1 = 0b000000001. Bitwise operators in C (when reading examples,) gives some time code that check specific bits by shifting the bits left and right to make every bit but the specific one to zeros. As I understand bitwise operators in python, this is not possible then?
