Question

早上好，

只要其中一个row1check变量变为True，while循环就会停止？我希望循环保持循环，直到所有3个变量都为True。我正确使用循环吗？

def x_turn ():
global row1check
global row2check
global row3check
while (row1check == False) and (row2check == False) and (row3check == False):
    move = raw_input("Player X Enter coordinates 'row,col': ")

    row = move[0]
    column = move[2]

    if row == "1" and column == "1" and row1[0] == " ":
        row1[0] = "x"
        draw_matrix()
        check_game()
        end_game()
        o_turn()
    if row == "1" and column == "2" and row1[1] == " ":
        row1[1] = "x"
        draw_matrix()
        check_game()
        end_game()
        o_turn()
    if row == "1" and column == "3" and row1[2] == " ":
        row1[2] = "x"
        draw_matrix()
        check_game()
        end_game()
        o_turn()
    if row == "2" and column == "1" and row2[0] == " ":
        row2[0] = "x"
        draw_matrix()
        check_game()
        end_game()
        o_turn()
    if row == "2" and column == "2" and row2[1] == " ":
        row2[1] = "x"
        draw_matrix()
        check_game()
        end_game()
        o_turn()
    if row == "2" and column == "3" and row2[2] == " ":
        row2[2] = "x"
        draw_matrix()
        check_game()
        end_game()
        o_turn()

Answer 1

您可以使用all功能：

while not all([row1check, row2check, row3check]):

只有在所有这些都为真时才会停止。

Answer 2

切换到or而不是and：

while (row1check == False) or (row2check == False) or (row3check == False):

这种方式只有当所有3个条件都是True时才会停止循环。

P.S您还可以使用all：

>>> data = [False, False, False]
>>> not all(data)
True

Answer 3

你的while循环语法是对的。但根据您的要求，您应该使用：

while (row1check == False) or (row2check == False) or (row3check == False):

在此处使用or意味着只要满足上述任何条件，它就应该继续运行代码。也就是说，row1check，row2check或row3check中的任何一个都是false。

Answer 4

你也可以像这样使用and运算符：

row1check = False
row2check = False
row3check = False

def x_turn():
    global row1check
    global row2check
    global row3check
    while not (row1check and row2check and row3check):
        print('Looping...')
        row1check = True
        row2check = True
        row3check = True

if __name__ == '__main__':
    x_turn()

当row1check，row2check，row3check都为True时停止while while循环。
