Question

我在文本文件中搜索密码，但是它说每次都找不到密码，尽管密码存在于文件中。

这是我目前的代码：

 import pickle
 import time      
    print "Do you already have a database created"
    y=raw_input("'yes' to continue")
    if y=='yes':               #to search password in text file
      infile=open(r"C:\Users\pc\Desktop\itika study material\cs\password.txt", "r") 
      Passwords = infile.readlines()

      while True:
        InputPassword = raw_input("Enter your password.")
        print "Searching for password."
        time.sleep(2)
        if InputPassword in Passwords:
            print "your password has been found, you can access your database"
            break
        else:
            print "your password has Not been found."    #only prints this statement
            break

Answer 1

可能是您的Passwords变量包含换行符而您的InputPassword数组不包含换行符。尝试使用非常简单的设置在调试器中查看它们以确认存在完全匹配。请记住，in函数必须完全匹配才能正常工作。

Answer 2

尝试使用Passwords = infile.read()代替Passwords = infile.readlines()。这将读取整个文件，并允许您搜索整个文件中的InputPassword字符串。

请注意，这不是对密码的安全检查。

在“ Passwords”变量中创建的列表中包含“ \ n”。只需去除\ n，它应该可以正常工作

这是正确的：

import pickle
import time
print("Do you already have a database created")
y = input("'yes' to continue")
if y == 'yes':  # to search password in text file
    Passwords = list(
        map(lambda x: x.strip(), (open(r"password.txt", "r")).readlines()))

    # Passwords = "infile"
    print(type(Passwords))
    print(Passwords)

    while True:
        InputPassword = input("Enter your password.")
        print("Searching for password: ", end=" ")
        print(InputPassword)
        time.sleep(2)
        if InputPassword in Passwords:
            print("your password has been found, you can access your database")
            break
        else:
            print("your password has Not been found.")
            break
