为什么我的自动生成代码有时会卡在中间？

Question

The code is as follows...

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

It is meant to create a file like this and delete then replace the old text within the file when it is run again:

b00
n41
e22
s33
s44
w15
x

it works sometimes but sometimes its gets stuck and i have no idea why

Chris_Rands，您使我意识到我要做的就是在while循环的开头添加cont = True 。
