    Instead of using input(), can you hardcode a known input that fails? Commented Mar 15, 2020 at 0:37

  • Please give us a minimal, reproducible example; don't expect every one of us to type input for you. Commented Mar 15, 2020 at 0:42
  • What is this program supposed to do? Why do you expect other output? It obviously works the way you programmed it -- computers are rather annoying in that respect. Commented Mar 15, 2020 at 0:43
  • @harveychoi this is actually an interesting question, but you've made it hard to understand. You can show a minimal example with just: a[a.index(1)], a[a.index(2)] = a[a.index(2)], a[a.index(1)] — you don't need all the input() business — and then simply ask why it is not swapping elements as you might expect.
