Bit manipulation in python
WebA technique they most certainly used is the manipulation of bitfields for some data structures because they are light and fast, especially much lighter in terms of memory and processing than the Python dictionaries and lists. They are not adapted for every use though: they are limited, trickier to get right, and not super easy to debug. WebJan 11, 2024 · Bit operators used to carry out the bit manipulation are the NOT, AND, OR and XOR. These operators work like the Boolean logic …

It copies a bit if it exists in either operand. It copies the bit if it is set in one operand but not both. It is unary and has the effect of 'flipping' bits. (~a ) = -61 (means 1100 0011 in 2's complement form due to a signed binary number.
Web4 bitwise logical operators: & (Bitwise AND), (Bitwise OR), ^ (Bitwise XOR), and ~ (Bitwise NOT). 3 bitwise shift operators: << (Left shift), >> (Sign-propagating right shift), and >>> (Zero-fill right shift). JavaScript's bitwise operators treat their operands as binary numbers -- sequences of 32 bits -- but return decimal numbers.
