How does Python's bitwise complement operator (~ tilde) work?

As an example, here's the representation of -2 in two's complement: (8 bits) The way you get this is by taking the binary representation of a number, taking its complement (inverting all the bits) and adding one. Two starts as 0000 0010, and by inverting the bits we get 1111 1101. Adding one gets us the result above.

Bitwise Operators in Python

Python’s bitwise operators let you manipulate those individual bits of data at the most granular level. You can use bitwise operators to implement algorithms such as compression, encryption, and error detection as well as to control physical devices in your Raspberry Pi project or elsewhere.

Python Bitwise Operators - GeeksforGeeks

Python Bitwise Not (~) Operator works with a single value and returns its one’s complement. This means it toggles all bits in the value, transforming 0 bits to 1 and 1 bits to 0, resulting in the one’s complement of the binary number. Example: Take two bit values X and Y, where X = 5= (101)2 . Take Bitwise NOT of X.

BitwiseOperators - Python Wiki

These are Python's bitwise operators. All of these operators share something in common -- they are "bitwise" operators. That is, they operate on numbers (normally), but instead of treating that number as if it were a single value, they treat it as if it were a string of bits, written in two's complement binary.

Top 4 Ways to Use the Tilde Operator in Python - sqlpey

Exploring the Tilde Operator ~ in Python. The tilde operator (~) holds a fascinating place in Python, primarily functioning as the bitwise complement operator. It not only flips bits but is also used creatively in various arithmetic and logical operations.

One way to create a complement from a pre-existing variable is to simply apply Python’s ~ unary negate operator. For example, let’s create a variable and its complement: All complements created from the same variable instance are not just identical, they all refer to the same object:

Find the complement of a number - Python Forum

1's complement: 1100 0011, that means the first 1 -> - and 100 0011 is 67. You work with one Byte (=8bit), 1 is already assigned, so 7 left. 2**7 = 128. You now substract (because this is a negative value and this is how negative values are represented in binary) this value of 67; 67-128 = -61.
