Splet19. jul. 2014 · 31. The canonical way to swap two variables in Python is. a, b = b, a. Please note than this is valid whatever the "type" of a or b is (numeric, string, tuple, object, ...). Of course, it works too if both variables reference values of different types. As many imperative languages, Python evaluates assignments right to left. In computer programming, the exclusive or swap (sometimes shortened to XOR swap) is an algorithm that uses the exclusive or bitwise operation to swap the values of two variables without using the temporary variable which is normally required. The algorithm is primarily a novelty and a way of demonstrating … Prikaži več Conventional swapping requires the use of a temporary storage variable.
