Chapter 2: AI with Search Techniques and Games

Activity 2: Teach the agent realize situations when it defends against losses

Follow these steps to complete the activity:

1. Create a function player_can_win such that it takes all moves from the board using the all_moves_from_board function and iterates over it using a variable next_move. On each iteration, it checks if the game can be won by the sign, then it return true else false.

   def player_can_win(board, sign):
       next_moves = all_moves_from_board(board, sign)
       for next_move in next_moves:
           if game_won_by(next_move) == sign:
               return True
       return False

2. We will extend the AI move such that it prefers making safe moves. A move is safe if the opponent cannot win the game in the next step.
