""" Python Bitwise Operators """
"""
& (and) - Sets each bit to 1 if both bits are 1
| (or) - Sets each bit to 1 if one of the bits is one
^ (xor) - Sets each bit to 1 if only one of two bits is 1
~ (not) - Inverts all the bits
<< (zero fill/left shift) - Shift left by pushing zeros in from the right and let the leftmost bits fall off
>>	(Signed/ right shift) - Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off
