I'm relatively new to python and as a beginner's project i made a simple tic tac toe game that runs in python shell.The script is a bit lengthy and the AI is fairly good but it's too easy to beat.Any comments and suggestions are welcome.
import string
import random
game=True #game variable
board=[] #board array
print """ Python Shell Tic-Tac-Toe--DeXtreme
Enter the column number-space-row number
to play.Four in a row to win"""
print "\n"
#make a 2D list
def makeboard():
for i in range(0,4):
board.append([])
for x in range(0,4):
board[i].append(" ")
printboard()
#computer AI
def complay(a=0,b=0):
choice=random.choice([0,1])
if choice==0:
play=True
while play==True:
n=random.choice([0,1,2,3])
m=random.choice([0,1,2,3])
if board[n][m]==" ":
board[n][m]="O"
print "Computer Has Played"
print "\n"
play=False
if choice==1:
play=True
while play==True:
