AttributeError：'str'对象没有属性'salt'

Question

我正在学习python，并且正在研究其中一个早期练习，并按照说明创建了所有内容并放置了字典文件并指出脚本在我的/ etc/passwd文件中，但不断收到此错误：

AttributeError: 'str' object has no attribute 'salt' 

这里是我使用的代码：

import crypt 
def testPass(cryptPass): 
    salt = cryptPass[0:2] 
    dictFile = open('dictionary.txt','r') 
    for word in dictFile.readlines(): 
     word = word.strip('\n') 
     cryptWord = crypt.crypt(word.salt) 
     if (cryptWord == cryptPass): 
      print "[+] Found Password: "+word+"\n" 
      return 
    print "[-] Password Not Found.\n" 
    return 
def main(): 
    passFile = open('/etc/passwd') 
    for line in passFile.readlines(): 
     if ":" in line: 
      user = line.split(":")[0] 
      cryptPass = line.split(":")[1].strip(' ') 
      print "[*] Cracking Password for: " +user 
      testPass(cryptPass) 
if __name__ == "__main__": 
    main()

您试图在字符串word使用salt属性：

cryptWord = crypt.crypt(word.salt) 
#      ^^^^^^^^^ 

你大概意思都使用逗号，在名称salt传递作为单独的参数：

cryptWord = crypt.crypt(word, salt)
