Python 如何屏蔽用户密码输入并将其另存为输出，以替换其他文件中的默认密码

我是python新手，不知道如何正确提问，所以请原谅我

真正需要指导的是，我想让用户使用输入输入他的密码，输出被屏蔽为星号，用户输入将用于更改另一个文件信息（我在windows 10上使用python 3）

我知道我可以使用getpass.getpass（）并将密码显示为星号是有风险的，因为它可以让其他人读取和计算密码的长度，但由于我想让这个小应用看起来“专业”，让用户感到安全，因此我认为有必要屏蔽密码

email = "mynewemail@gmail.com"  
password = "mynewpassword12345"          
user = "mynewnewid1"
seefirst1 = "newid1" 
seefirst2 = "newid2"  
seefirst3 = "newid3"  
seefirst4 = "newid4" 
seefirst5 = "newid5" 
seefirst6 = "newid6"  
seefirst7 = "newid7"  
seefirst8 = "newid8" 
seefirst9 = "newid9"  
seefirst10 = "newid10"  

email = "mynewemail@gmail.com"  
password = ""          
user = "mynewnewid1"
seefirst1 = "newid1" 
seefirst2 = "newid2"  
seefirst3 = "newid3"  
seefirst4 = "newid4" 
seefirst5 = "newid5" 
seefirst6 = "newid6"  
seefirst7 = "newid7"  
seefirst8 = "newid8" 
seefirst9 = "newid9"  
seefirst10 = "newid10"

最后，应该保存输出以替换另一个文件基本信息，如电子邮件、用户id和密码

email = "mynewemail@gmail.com"  
password = "mynewpassword12345"          
user = "mynewnewid1"
seefirst1 = "newid1" 
seefirst2 = "newid2"  
seefirst3 = "newid3"  
seefirst4 = "newid4" 
seefirst5 = "newid5" 
seefirst6 = "newid6"  
seefirst7 = "newid7"  
seefirst8 = "newid8" 
seefirst9 = "newid9"  
seefirst10 = "newid10"  

email = "mynewemail@gmail.com"  
password = ""          
user = "mynewnewid1"
seefirst1 = "newid1" 
seefirst2 = "newid2"  
seefirst3 = "newid3"  
seefirst4 = "newid4" 
seefirst5 = "newid5" 
seefirst6 = "newid6"  
seefirst7 = "newid7"  
seefirst8 = "newid8" 
seefirst9 = "newid9"  
seefirst10 = "newid10"

我成功地替换了除密码外的所有密码，因为它只将输入的密码（mynewpassword12345）更改为“”

下面是我从SO获得的示例代码示例，回答将用户密码屏蔽为星号（但很抱歉，我忘记保存链接）

它在python exe上工作（但不是在空闲时），并将用户密码输入屏蔽为星号，但它不允许我将打印的密码保存为用户输出

请帮我解决这个问题。我是个新手，对python非常陌生。

抛开方法中的其他问题不谈，我将关注您的“不想要的结果：屏蔽输入密码没有取代默认密码。”

您有一个全局的

list1

，您还可以在

getPASS（）

函数中定义一个

list1

，从该函数返回后要使用该函数。这不能按原样工作，因为函数中的

list1

是本地的，并且与全局的

list1

不同。我建议从函数返回一个适当的值，e。g、 :

def getPASS():
    print("Input password")
    list1 = []
    while True:
        …
    return "".join(list1)

…
psw = getPASS()

密码输入和验证的逻辑在这里混淆了：

psw = "".join(list1)
print(psw)
invalid = ' ,:;/?"\}]{[-=+!@#$%^&*()|'
for x in psw:
    if x in invalid:
        print("Character %r is not allowed in password" % x)
        getPASS()
    else:
        pass

getPASS()

您试图在调用

getPASS（）

输入密码之前分配并验证密码，因此

psw

为空。重新安排，e。G（假设上述1.更改为

getPASS（）

）：

谢谢，非常感谢阿玛利爵士，没有他的指导，这个问题是无法解决的

下面是我编辑的剧本的结果，正如阿玛利爵士在他被接受的答案中所建议的那样。（我不会接受我被接受的答案，只是作为对这部分感兴趣的人的参考。）

如果密码最终以明文形式存在于文本文件中，则无论如何，安全性都是一个丢失的原因。密码最终将存在于文本文件中，但在此结束时，上述基本脚本将自动删除提取/修改的文件。它也会创建新的PYC文件（是的，我知道这个PYC在一个可以解码的地方也是不安全的，但是我认为它应该足够让用户认为它是安全的（用户是非编码人）”“让用户假设它是安全的”。如果不是，那是非常不道德的。布鲁诺·德舒利尔斯爵士，谢谢你的评论，我接受这一建议。实际上，我让用户自己在自己的电脑上使用经过编码的pyc脚本。作为一名基础学习者，我现在仍然不知道如何制作一个安全的脚本，我还有很多东西要做我自己无法解决这些问题，这就是为什么我来这里向您和更多高级编码人员学习的原因。谢谢您的回答，先生。我在几个小时前阅读了您的解决方案，最后在这里和那里进行了几个小时的更改后，我成功地按照您的建议完成了这项工作。非常感谢先生。（我已尝试将您的答案作为可接受的答案，但由于我尚未达到至少15个代表，我现在无法这样做。）
