Answer to Question #199865 in Python for ken

Question

Implement the following features:

• the board should be stored as a three-element list, while each element is another three-element list (the inner lists represent rows) so that all of the squares may be accessed using the following syntax:

board[row][column]

• each of the inner list's elements can contain 'O', 'X', or a digit representing the square's number (such a square is considered free)
• the board's appearance should be exactly the same as the one presented in the example.

Drawing a random integer number can be done by utilizing a Python function called randrange(). The example program below shows how to use it (the program prints ten random numbers from 0 to 8).

Note: the from-import instruction provides an access to the randrange function defined within an external Python module called random.

from random import randrange

for i in range(10):

   print(randrange(8))
