Bits in python
WebMay 4, 2024 · I want to parse some data with Python and scapy. Therefor I have to analyse single bits. But at the moment I have for example UDP packets with some payload like: bytes = b'\x18\x00\x03\x61\xFF\xFF\x00\x05\x42\xFF\xFF\xFF\xFF' Is there any elegant way to convert the bytes so that I can access single bits like: WebJan 11, 2024 · To show this with a small example, if one wanted to represent the number -6: 6-1 gives 5, and 5 in binary is 0101; Switching all the bits, it becomes 1010, which is the two’s complement representation of –6. The respective symbols used in Python to perform these bit operations are as follows: Left Shift. <<. Right Shift.
