My code works fine inside the python shell, but not showing anything when running it on my Visual studio code

Question

The code works inside Python shell, but not inside VS Code terminal. Can anyone please help me, I am about to go nuts.

I have tested my code on several ide and it works fine, just on VS 

board = ["  " for i in range(9)]


def print_board():
    row1 = "| {} | {} | {} |".format(board[0], board[1], board[2])
    row2 = "| {} | {} | {} |".format(board[3], board[4], board[5])
    row3 = "| {} | {} | {} |".format(board[6], board[7], board[8])

    print(row1)
    print(row2)
    print(row3)
    print()


def player_move(icon):

    if icon == "X":
        number = 1
    elif icon == "O":
        number = 2

    print("Your turn player {}".format(number))

    choice = int(input("Enter your move (1-9): ").strip())
    if board[choice - 1] == "  ":
        board[choice - 1] = icon
    else:
        print()
        print("That space is taken!")

I need to see the board that I have created, it simply does not show anything inside VS code

It simply does not show anything inside the terminal and I don't get any errors.

while you define your print statements in print_board() you never actually call it.

Just add

print_board()

to the end and wherever appropriate.

so your code might look something like:

import numpy as np

board = [" " for i in range(9)]
icons = {1:"X", 2:"O"}

def print_board(remove=0):
    if remove > 0:
        print('\x1b[1A\x1b[2K'*remove)
    boardString = "| {} | {} | {} |\n"*3
    print(boardString.format(*board))


def player_move(_turn):
    player = np.mod(_turn,2)+1
    print("Your turn player {}".format(player))

    while True:
        choice = int(input("Enter your move (1-9): "))
        if board[choice - 1] == " ":
            board[choice - 1] = icons[player]
            break
        else:
            print('\x1b[1A\x1b[2K'*3)
            print("That space is taken!")

    print_board(7)

print_board()
for turn in range(9):
    player_move(turn)

| X | O | X |
| O |   |   |
|   |   |   |

Your turn player 1
Enter your move (1-9):

some notes:

As shown above, you can replaces the last print of the board and command prompt by utilising VT100 codes for going up a line (\x1b[1A) and removing a line (\x1b[2K) before printing anew
strings can be multiplied (repeated) like lists

In [1]: print('a'*3)                                                                      
> aaa

you can add \n for a line break to strings instead of calling print() multiple times

In [25]: print('a\nb')                                                              
> a
> b

you can unpack iterable variables (lists, tuples..) by using * or **

yourDict = {'a':3, 'b':4}
yourList = [1, 2]

yourFun(*yourList, **yourDict )
# is equvivalent to:
yourFun(1, 2, a=3, b=4 )
