From temp variables and XOR hacks to the elegant mechanics of Python’s one-liner.


Swapping the values of two variables is one of the very first logic puzzles we learn in programming. In most languages, it requires a bit of gymnastics. But in Python, it feels like pure magic:

a, b = b, a
Have you ever stopped to wonder _how_ this actually works without destroying the data along the way? Today, let’s put on our detective hats and investigate the four different ways to solve the swap puzzle — and see why Python’s one-liner
