Tic-tac-toe or noughts and crosses is a paper-and-pencil game for two players who take turns marking the spaces in a three-by-three grid with X or O. The player who succeeds in placing three of their marks in a horizontal, vertical, or diagonal row is the winner.

The board should be implemented using nested lists.
This is an example of the board:

 column   
 1  2  3   
[ ][ ][ ]  row 1   
[ ][ ][ ]  row 2   
[ ][ ][ ]  row 3  

• To create a movement you need to type the first value for the row(1-3) then click Enter and then type the value for the column(1-3) and click Enter.
• The program moves after you and your moves and the program’s moves are immediately displayed.

Left 9 moves
Select a row (1-3)2
Select a column (1-3)3
Your move:
[ ][ ][ ]
[ ][ ][X]
[ ][ ][ ]
Program move:
[ ][ ][0]
[ ][ ][X]
[ ][ ][ ]
Left 7 moves
Select a row (1-3)

Function testForFreeCell() display how many free moves are left. If there are no free cells, it will be a draw.

def testForFreeCell():
  
    empty=0
    for i in range(0,3):
        for j in range(0,3):
            if field[i][j]==' ':
                empty+=1
    return empty
while True:
    if testForFreeCell()==0:
        print("Draw")
        break

Game tactics of the program "Random selection", this leaves room for improvement in program tactics.
