Python 2.7 为什么可以'；我不能得到一个退出命令来工作吗

您好，我是Python2.7.3的新手，我正在尝试在两个if语句之后编写一个自动退出子句

import os

password = "Anhur"
attempt = 0
while (password != "Anhur") and (attempt <= 3):
    password = raw_input("Password: ")
    attempt = attempt + 1
    if attempt == 3:
        print ("You have used all your attempts, the system will now close..")
        print (" The shifting sands have ended you.")
        break

if (password == "Anhur"):
    print ("You conquered the sands")

os.exit(1)

导入操作系统
password=“Anhur”
尝试=0
而（密码！=“Anhur”）和（尝试只需使用
exit（）


导入操作系统
password=“”
尝试=0
而（密码！=“Anhur”）和（尝试Hi，
有用的答案。不过，初始代码有缺陷且毫无用处。请尝试以下代码：

import os

password = ""
attempts = 0
found = False
while (attempts <= 2):
    password = raw_input("Password: ")
    attempts = attempts + 1
    if (password == "Anhur") :
        found = True
        break

if found:
    print ("You conquered the sands")
    exit(0)
else:
    print ("You have used all of your attempts, the system will now close..")
    print (" The shifting sands have ended you.")
    exit(1)

导入操作系统
password=“”
尝试次数=0
发现=错误
而
import os

password = ""
attempts = 0
found = False
while (attempts <= 2):
    password = raw_input("Password: ")
    attempts = attempts + 1
    if (password == "Anhur") :
        found = True
        break

if found:
    print ("You conquered the sands")
    exit(0)
else:
    print ("You have used all of your attempts, the system will now close..")
    print (" The shifting sands have ended you.")
    exit(1)
