我的代码在python shell中运行良好，但在我的Visual Studio代码上运行它时没有显示任何内容

Question

代码在Python shell中运行，但不在VS Code终端内部。 任何人都可以帮助我，我准备好了。

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!")

我需要看到我创建的主板，它根本没有在VS代码中显示任何内容

它根本没有在终端内显示任何内容，我也没有任何错误。

当你在print_board()定义你的print语句时，你实际上从来没有调用它。

只需添加

print_board()

到最后和适当的地方。

所以你的代码可能看起来像：

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): 

一些说明：

• 如上所示，您可以使用VT100代码上一行（ \\x1b[1A ]并删除一行（ \\x1b[2K ），然后重新打印），替换最后一次打印的电路板和命令提示符
• 字符串可以像列表一样倍增（重复）

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

• 你可以为字符串添加\\n ，而不是多次调用print()

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

• 您可以使用*或**解压缩可迭代变量（列表，元组..）

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

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