Python登录脚本；用户名和密码在单独的文件中 [英] Python Login Script; Usernames and Passwords in a separate file

问题描述

我正在寻求帮助，以使我的Python脚本模仿登录功能，同时将凭据存储在单独的文件中.

I'm looking for assistance to get my Python script to imitate a log-in feature while the credentials are stored in a separate file.

我可以通过硬编码的用户名和密码来使用它，并且它还可以读取文件，但是我在寻找如何将两者链接在一起方面遇到了一些困难.

I got it to work from hard-coded Username and Password, and it also reads in a file, but I'm having some difficulty finding out how to link the two together.

我们将为您提供任何帮助.

Any assistance is appreciated.

Python脚本如下:

The Python script is as follows:

print "Login Script"

import getpass

CorrectUsername = "Test"
CorrectPassword = "TestPW" 

loop = 'true'
while (loop == 'true'):

    username = raw_input("Please enter your username: ")

    if (username == CorrectUsername):
        loop1 = 'true'
        while (loop1 == 'true'):
            password = getpass.getpass("Please enter your password: ")
            if (password == CorrectPassword):
                print "Logged in successfully as " + username
                loop = 'false'
                loop1 = 'false'
            else:
                print "Password incorrect!"

    else:
        print "Username incorrect!"

我在其他地方找到了这个文件，帮助我读取了文件，它确实打印了文本文件的内容，但是我不确定如何从此继续进行工作:

I found this somewhere else that helped me read the file in, and it does print the contents of the text file, but I am unsure on how to progress from this:

with open('Usernames.txt', 'r') as f:
    data = f.readlines()
    #print data

for line in data:
    words = line.split() 

文本文件包含以下格式的用户名和密码:Test:TestPW Chris:ChrisPW Admin:AdminPW，每个凭据都位于新行上.

The text file contains the Usernames and Passwords in a format of: Test:TestPW Chris:ChrisPW Admin:AdminPW with each credential on a new line.

正如我之前所说，任何帮助都将不胜感激！ 谢谢.

As I said previously, any help is appreciated! Thanks.

推荐答案

您可以开始使用用户名和密码的字典:

You could start having a dictionary of usernames and passwords:

credentials = {}
with open('Usernames.txt', 'r') as f:
    for line in f:
        user, pwd = line.strip().split(':')
        credentials[user] = pwd

然后您有两个简单的测试:

Then you have two easy tests:

username in credentials

会告诉您用户名是否在凭据文件中(即，它是否是credentials词典中的密钥)

will tell you if the username is in the credentials file (ie. if it's a key in the credentials dictionary)

然后:

credentials[username] == password
