Jul 1, 2015 · 15 Python bitwise ~ operator invert all bits of integer but we can't see native result because all integers in Python has signed representation. Indirectly we can examine that:

May 14, 2022 · Bitwise negating 0101 gives 1010. With 1 in most significant bit, python interprets it as a negative number in 2's complement form and to get back corresponding decimal it further takes 2's …

~ is bitwise NOT. Specifically, for standard Python ints, it's signed, bignum bitwise NOT. You seem to be expecting 5-bit unsigned bitwise NOT, for some reason.

May 15, 2022 · Per-spec: The unary (invert) operator yields the bitwise inversion of its integer argument. The bitwise inversion of is defined as . because semantically Python's integers are always signed …

It performs a bitwise inversion on the binary representation of a number. In most programming languages, including Python, integers are represented using a fixed number of bits, typically 32 or …

Nov 17, 2009 · x | 2 # Bitwise OR: 0011 # Result: 3 x & 1 # Bitwise AND: 0001 # Result: 1 I can understand the arithmetic operators in Python (and other languages), but I never understood 'bitwise' …

Nov 24, 2021 · Bitwise not (~) is well-defined in languages that define a specific bit length and format for ints. Since in Python 3, ints can be any length, they by definition have variable number of bits.

Bitwise works on the binary level, so 0 on binary would seen as 0000_0000, and (in two's complemented) -1 is 1111_1111, this not 0 flips all the bits to 1s, thus alters 0 into -1.

Sep 28, 2016 · There are no hooks for and or or operators, no (as they short-circuit), and there is no xor operator in Python. The __and__ and __or__ are for the bitwise & and | operators, respectively. The …

Jan 18, 2022 · Since Python ints are both signed and not a defined size of bits, the easiest way is to just XOR with an all 1's mask of the required bit length. For example to get a NOT for 4 bits:
