The final result is 1.Īlternatively, if you want to perform a bitwise XOR on all elements in a set, you can use the same idea of importng the NumPy library using import numpy as np and calling np.bitwise_xor.reduce(my_set). Then, you use the result and compare it with the next row, and so on. If they’ve different bits, the intermediate result is 1, otherwise 0. To calculate this, you have to perform XOR along each given column, two rows at a time. You can see the computation in the following table-the last row being the result of the bitwise XOR operation on all elements in the list that correspond to binaries 0001, 0010, 0011, 0100, and 0101. To perform a bitwise XOR operation on all elements in a given list of integers, import the NumPy library using import numpy as np and call np.bitwise_xor.reduce(my_list). You can see those examples in the following script: > 0 ^ -1 Here’s the result of the bitwise XOR operator x ^ y when applied to example negative integer operands x and y: x (int) Let’s use this knowledge in a couple of examples to showcase the working of the bitwise XOR operator on negative integers: Python Bitwise XOR ^ Examples on Negative Integers Then, you complement all bits to determine the negative (complementary) binary "11110110". To represent x = -10 using 8 bits you first calculate (10-1) = 9 which is "00001001" in binary format.To represent x = -1 using 8 bits you first calculate (1-1) = 0 and then flip all bits to calculate "11111111".You write a negative number -x as the bit pattern for (x-1) and flip all bits from 1 to 0 and from 0 to 1 (complement). The first bit of a complementary binary is the sign (0: positive, 1: negative). Python uses so-called complementary binaries to represent negative integers. This will boost your computer science skills, so keep reading! ?? Representing Negative Integers in Binaries But first, you need to understand how negative integers are represented in the first place.

Next, you’ll learn how to use the operator on negative integers. You can see those examples in the following Python script: > 0 ^ 1 Here’s the result of the bitwise XOR operator x ^ y when applied to a couple of example integer operands x and y: x (int)
