Python lets you assign multiple variables in one line: python x, y, z = 1, 2, 3 # x is 1, y is 2, z is 3 a = b = c = 0 # All three are 0 This is useful for swapping values.
In most languages, you need a temp variable: python # Other languages temp = x x = y y = temp # Python x, y = y, x # Swap in one line The right side is evaluated completely before assignment, so the swap works correctly.
