Drawing the Board Data Structure on the Screen
6. def drawBoard(board):
7. # This function prints out the board that it was
passed. Returns None.
8. HLINE = ' +---+---+---+---+---+---+---+---+'
9. VLINE = ' | | | | | | | | |'
10.
11. print(' 1 2 3 4 5 6 7 8')
12. print(HLINE)
The
drawBoard()
function will print out the current game
board
based on the data
structure in board. Notice that each square of the board looks like this:
+---+
| |
| X |
| |
+---+
Since we are going to print the string with the horizontal line (and plus signs at the
intersections) over and over again, we will store that in a constant variable named
HLINE
.
There are also lines above and below the very center of X or O tile that are nothing but '|'
characters (called "pipe" characters) with three spaces in between. We will store this string
in a constant named
VLINE
.
Line 11 is the first
print()
function call executed, and it prints out the labels for the
X-axis along the top of the board. Line 12 prints the top horizontal line of the board.
