Python 为什么我的自动生成代码有时会中途卡住？

代码如下

import random
file_name = 'room_gen'
room_no = 0
direction = 0
cont = True
method = "a"

while room_no != 6:
    last_dir = direction
    direction = random.randrange(1,5)
    print(direction)
    layout = random.randrange(2,6)
    if room_no == 0:
        direction = 'b'
        layout = 0
        method = "w"
    elif room_no == 5:
        layout = 1
    else:
        if direction == 1:
            direction = 'n'
        elif direction == 2:
            direction = 'e'
        elif direction == 3:
            direction = 's'
        elif direction == 4:
            direction = 'w'
    if direction == 'n' and last_dir == 's':
        cont = False
    elif direction == 's' and last_dir == 'n':
        cont = False
    elif direction == 'e' and last_dir == 'w':
        cont = False
    elif direction == 'w' and last_dir == 'e':
        cont = False
    if cont == True:
        direction = str(direction)
        layout = str(layout)
        room_no = str(room_no)
        file = open((file_name),(method))
        write = (direction + layout + room_no + "\n")
        file.write(write)
        room_no = int(room_no)
        file.close()
        room_no = room_no + 1
        method = "a"

file = open((file_name),"a")
write = ("x")
file.write(write)
file.close

这意味着创建一个类似这样的文件，并在再次运行时删除然后替换文件中的旧文本：

b00
n41
e22
s33
s44
w15
x

它有时会工作，但有时会卡住，我不知道为什么

克里斯•兰兹，你让我意识到我所要做的就是在while循环的开头添加一个

cont=True

。

当你将

cont

更改为

False

时，

room\u no

从不递增，因此您会陷入

循环，而
循环将其作为答案，因为它包含答案
