Nov 17, 2009 · Bitwise operators are operators that work on multi-bit values, but conceptually one bit at a time. AND is 1 only if both of its inputs are 1, otherwise it's 0. OR is 1 if one or both of its inputs are 1, otherwise it's 0.
Bitwise operations on Python ints work much like in C. The &, | and ^ operators in Python work just like in C. The ~ operator works as for a signed integer in C; that is, ~x computes -x-1. You have to be somewhat careful with left shifts, since Python integers aren't fixed-width. Use bit masks to obtain the low order bits.
Apr 26, 2009 · In most programming languages, including Python, integers are represented using a fixed number of bits, typically 32 or 64. I am just using example of 8 bit (for fast and better understanding). The binary representation of 2 is "00000010" (8 bits), and the bitwise NOT of 2 would invert each bit, resulting in "11111101".
Feb 27, 2012 · 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:
Mar 23, 2014 · I got two objects, a and b, each containing a single byte in a bytes object. I am trying to do a bitwise operation on this to get the two most significant bits (big-endian, so to the left). a = s...
Bitwise operators are useful for looping arrays which length is power of 2. As many people mentioned, bitwise operators are extremely useful and are used in Flags, Graphics, Networking, Encryption. Not only that, but they are extremely fast. My personal favorite use is to loop an array without conditionals.

Oct 2, 2010 · Use boolean (logical) operators with boolean operands, and bitwise operators with (wider) integral operands (note: False is equivalent to 0, and True to 1). The only "tricky" scenario is applying boolean operators to non boolean operands. Let's take a simple example: 5 & 7 vs. 5 and 7. For the bitwise and (&), things are pretty straightforward:
Mar 16, 2016 · If doing cryptographic or other similar data manipulation operations in Python you want to be able to do this on strings of bytes. In my opinion Python3 should support this operation on byte strings. – Omnifarious
