Beginner tic-tac-toe

Python Help
1

Hello, I am new to Python and started coding a tic-tac-toe game. When it comes to alternating between player turns, I couldn’t find a solution not to change the turn when the player enters his own number into a already occupied place filled with his same number.
I would really appreciate your feedbacks.

Here is my code:

import numpy as np

row_count = 3
col_count = 3

def create_board():
board = np.zeros((row_count, col_count))
return board

def is_valid_location(board, row, col):
return board[row][col] == 0

def drop_piece(board, row, col, piece):
board[row][col] = piece

def show_board(board):
print(np.flip(board, 0))

def winning_move(board, piece):
for c in range(col_count):
for r in range(row_count - 2):
if board[r][c] == piece and board[r + 1][c] == piece and board[r + 2][c] == piece:
return True

for c in range(col_count - 2):
    for r in range(row_count):
        if board[r][c] == piece and board[r][c + 1] == piece and board[r][c + 2] == piece:
            return True

for c in range(col_count - 2):
    for r in range(row_count - 2):
        if board[r][c] == piece and board[r + 1][c + 1] == piece and board[r + 2][c + 2] == piece:
            return True

for c in range(col_count - 2):
    for r in range(2, row_count):
        if board[r][c] == piece and board[r - 1][c + 1] == piece and board[r - 2][c + 2] == piece:
            return True

board = create_board()

turn = 1

show_board(board)

running = True
while running:

if turn == 1:

    row = int(input("Player 1 Select A Row (0-2): "))
    col = int(input("Player 1 Select A Column (0-2): "))





    if is_valid_location(board, row, col):
        drop_piece(board, row, col, 1)




    if winning_move(board, 1):
        show_board(board)
        print("Player 1 Won, Congrats!!")
        break





    show_board(board)





    turn += 1










if turn == 2:

    row = int(input("Player 2 Select A Row (0-2): "))
    col = int(input("Player 2 Select A Column (0-2): "))



    if is_valid_location(board, row, col):
        drop_piece(board, row, col, 2)

    if winning_move(board, 2):
        show_board(board)
        print("Player 2 Won, Congrats!!")
        break


    show_board(board)


    turn -= 1
2

You write this:

What happens if it is and invalid location is that it checks for a winning move ==> unecessary, it shows the board ==> hasn’t changed, and it switches turn ==> we do not want that.

So just code

    if is_valid_location(board, row, col):
        drop_piece(board, row, col, 1)
    else:
        print("that is an invalid move, try again")
        continue

…and the turn is repeated.

You also have to do that for player 2.

You repeat the code for both players almost exactly alike. Maybe write it once and pass in whose turn it is?

Your suggestion runs smoothly. Thank you very much.
