Bitwise expression in python
WebDec 7, 2011 · On the other hand, bitwise operators perform an operation on every single bit of the two operands (hence the term "bitwise"). Ex: int x = 5; int y = 8; printing x y (bitwise OR) would calculate this: 00 0101 (5) 1000 (8) ----------- = 1101 (13) Meaning it would print 13.
