This is a Tic Tac Toe game written using the python programming language. This is a Tic Tac Toe game in which two players alternately put Xs and Os in compartments of a figure formed by two vertical lines crossing two horizontal lines and each tries to get a row of three Xs or three Os before the opponent does.

**Code:**

sq = ['o','1','2','3','4','5','6','7','8','9']
player = 1
choice = 0
win = -1
while(win == -1):
print"\tTic Toc Toe Game\n\n"

print("_____|_____|_____\n")
print(" | | ")
print(" " + sq[4]+" | " +sq[5] + " | " + sq[6] + "\n")
