I’m having problems getting the “Next” button to activate when I do this.

I originally just uncommented the code at the end.

I then re-commented it and started coding, having read the instructions more carefully. I leapt straight to returning the minimax results inside select_move - so I was only explicitly adding my choices into the code. Got to the end of the game - no “Next”.

I then tried printing the computer’s minimax results, then adding each result into the code, in case that was what you were looking for. Still no “Next”

I then swapped all the comments around again. Still no joy.

What have I missed? I want to get to stage ten!

Hey try this:

  1. You’re on exercise 9/10 now
  2. Click ‘back’ to get back to exercise 8/10
  3. You’re on exercise 8/10 now
  4. Click ‘next’ very quickly in succession to get to 10/10

If the link doesn’t change it is this:

can someone explain to me why [1] is used behind minimax()[1], please?

The function (minimax) returns a list of 2 numbers, which are-
[best_value, best_move]

so if you want to get the best_move out of the list then you’d have to check the first index of the list where it resides.
