WebApr 4, 2024 · In Python, bitwise operators are used to perform bitwise calculations on integers. The integers are first converted into binary and then operations are performed on each bit or corresponding pair of bits, hence the name bitwise operators. The result is then returned in decimal format. Note: Python bitwise operators work only on integers. WebNov 25, 2013 · I know in Python I can do it by getting the bin(n), truncating the string by 1, and then recasting it to an int, but I am curious if there is a more "mathematical" way to do this. e.g. say the number is 6, which is 110 in binary. Chop the first bit …
