如何在Python中修复while循环

问题描述 投票:0回答:1

我已经看到,通常,在while循环内使用while时会发生错误,但是,情况并非如此,因此我正在寻求有关“常见”错误的帮助

下面的代码部分并不重要,也许您可​​以忽略它

crd = ['1 3', '2 3', '3 3', '1 2', '2 2', '3 2', '1 1', '2 1', '3 1']
inp = list(input('Enter cells:'))
wins = 0
result = False


def field(val):
    print('---------')
    for i in range(0, 9, 3):
        print('| ' + '{} {} {}'.format(val[i], val[i+1], val[i+2]).replace('_', ' ') + ' |')
    print('---------')


def win(con):
    global wins
    global result
    if inp[0] == '_':
        result = 'Impossible'
    else:
        win_con = [[con[i], con[i+1], con[i+2]] for i in range(0, 9, 3)] \
                + [[con[i], con[i+3], con[i+6]] for i in range(0, 3, 1)]\
                + [[con[0], con[4], con[8]], [con[2], con[4], con[6]]]

        for i in win_con:
            if (set(i) == {'X'} or set(i) == {'O'}) and wins == 1:
                result = 'Impossible'
            elif set(i) == {'X'}:
                result = 'X wins'
                wins = 1
            elif set(i) == {'O'}:
                result = 'O wins'
                wins = 1

        if result == False:
            try:
                inp.index('_')
                result = 'Game not finished'
            except:
                result = 'Draw'
    print(result)


field(inp)

Bellow是代码的一部分,带有返回无限循环的循环错误(据我所知,错误在def move()部分中)>

def move():
    move = input('Enter the coordinates:').split(' ')
    while True:
        for n in move:
            if int(n) not in range(1, 4):
                print('Coordinates should be from 1 to 3!')
                move = input('Enter the coordinates:').split(' ')
                continue
            elif int(n) in range(1, 4):
                move = ' '.join(move)
                break


while True:
    move()
    position = [p for p, x in enumerate(crd) if x == move]
    int_pos = int("".join([str(p) for p in position]))

    if inp[int_pos] == '0' or inp[int_pos] == 'X':
        print('This cell is occupied! Choose another one!')
        move()
    elif inp[int_pos] == '_':
        inp[int_pos] = 'X'
        field(inp)
        win(inp)
    if result:
        break

以某种方式,即使我什至设法解决了无限循环错误,仍然出现了另一个问题-在检查了第一对坐标(并显示它们在范围之外)之后,输入了新的坐标对,但是仍然继续检查已经检查过的一对旧坐标。

我已经看到,通常在while循环内使用while时会发生错误,但是,在这里情况并非如此,因此我正在寻求有关此“常见”错误的帮助。 。

我猜你是在使用函数move只是为了输入有效的坐标您可以将其简化如下
