WebI'm not sure there is a "real" binary number underneath modern python integers. Python 2.5 and later had two types of integer values, int and long.The int value was the traditional 32 or 64 bit integer representation and the long was a "bignum" representation that allowed integer values far beyond the int maximum value. In python 3 the old int was removed … WebBackground Bitwise NOT ~ Python’s bitwise NOT operator ~x inverts each bit from the binary representation of integer x so that 0 becomes 1 and 1 becomes 0. This is semantically the same as calculating ~x == -x-1. For example, the bitwise NOT expression ~0 becomes -1, ~9 becomes -10, and ~32 becomes -33. buy home improvement complete series https://jrwebsterhouse.com
