Write a Program to implement Tic-Tac-Toe game using Python.
SOURCE CODE :
# Tuple to store winning positions.
win_positions = (
(0, 1, 2), (3, 4, 5), (6, 7, 8),
(0, 3, 6), (1, 4, 7), (2, 5, 8),
(0, 4, 8), (2, 4, 6)
)

print("\n", " | ".join(mesh[:3]))
print("---+---+---")
print("", " | ".join(mesh[3:6]))
print("---+---+---")
print("", " | ".join(mesh[6:]))
# Loop until player valid input cell number.
while True:

break
except ValueError:

# Return winning positions if player wins, else None.
for wp in win_positions:

print(f"*** Player {player} won! ***")
break

else:
# 9 moves without a win is a draw.
print("Game ends in a draw.")
OUTPUT :
Sample Output: 1 | 2 | 3 ---+---+--- 4 | 5 | 6 ---+---+--- 7 | 8 | 9 Enter player X's choice : 5 1 | 2 | 3 ---+---+--- 4 | X | 6 ---+---+--- 7 | 8 | 9 Enter player O's choice : 3 1 | 2 | O ---+---+--- 4 | X | 6 ---+---+--- 7 | 8 | 9 Enter player X's choice : 1 X | 2 | O ---+---+--- 4 | X | 6 ---+---+--- 7 | 8 | 9 Enter player O's choice : 6 X | 2 | O ---+---+--- 4 | X | O ---+---+--- 7 | 8 | 9 Enter player X's choice : 9 X | 2 | O ---+---+--- 4 | X | O ---+---+--- 7 | 8 | X *** Player X won! ***
