How the Code Works
The Game Board Data Structure
Before we get into the code, we should talk about the board data structure. This data
structure is a list of lists, just like the one in our previous Sonar game. The list is created so
that
board[x][y]
will represent the character on space located at position
x
on the X-axis
(going left/right) and position
y
on the Y-axis (going up/down). This character can either be
a
' '
space character (to represent a blank space), a
'.'
period character (to represent a
possible move in hint mode), or an
'X'
or
'O'
(to represent a player's tile). Whenever you
