Prerequisites

To complete this exercise, you need to know Python basics such as lists, conditions, loops, and functions.

Statement

• We’re building a console Tic Tac Toe game playable against a computer
• The board is a 3x3 grid numbered from 1 to 9 so that we can ask the player a cell to play by number.
• There is no A.I., the computer is playing random.

Tips

• We can modelize the board with a list of characters which can be either “X”, “O” or an empty string.
• To generate random numbers, we import Python’s random package and we use the randint(a, b)function which generates an int between a and b.

import random
random.randint(1, 10)
# 3

• The game should be played this way :

1. Board drawing.
2. The player is asked which square he wants to play.
3. Update the board according to the chosen square.
