python中的文件迭代问题

Question

我有一个任务，其中有两个文件，即“user.txt”、“pwd.txt”，现在我想基本上遍历这些文件的每个值，即“John”和“pwd.txt”中的所有值，然后是“user.txt”中的另一个值，所有值都是“pwd.txt”。

这里我想实现线程。

这是我的代码，

import threading

f1 = open("user.txt", "r")

f2 = open("pwd.txt", "r")

threads = []

def brute():

    for letter in f1.readlines():

        print "[+]First Value: {}".format(letter)

        for second_letter in f2.readlines():

            print "[+]Second Value: {}".format(second_letter)

        

            threads.append(threading.Thread(target=runner, args=(letter,second_letter,)))

for thread in threads:

    thread.start()

for thread in threads:

    thread.join()

    

def runner(word1,word2):

    print("[+]I am just a worker class: {0}:{1}".format(word1,word2))

输出来了

[+]First Value: john

[+]Second Value: test1234

[+]Second Value: socool!

[+]Second Value: abcde1234

[+]Second Value: password1

[+]Second Value: Passw0rd

[+]Second Value: adminRocks

[+]First Value: dean

[+]First Value: harry

[+]First Value: sam

[+]First Value: joseph

[+]First Value: rick

[+]I am just a worker class: john:test1234

[+]I am just a worker class: john:socool!

[+]I am just a worker class: john:abcde1234

[+]I am just a worker class: john:password1

[+]I am just a worker class: john:Passw0rd

[+]I am just a worker class: john:adminRocks

我不确定如何在此处使用密码文件中的所有密码打印所有用户值。非常感谢任何帮助。

根据您的帖子，目标是交叉加入用户和密码文件。为此，在 pwd 文件中加载一次，然后处理每个用户（每个线程一个）。请注意，我使用 Python 3.8 对此进行了测试。试试这个代码：import threading# create files for testinguser = "user1\nuser2\nuser3\nuser4\nuser5\nuser6\nuser7\nuser8\nuser9"pwd = "pwd1\npwd2\npwd3\npwd4\npwd5\npwd6\npwd7\npwd8\npwd9"with open("user.txt",'w') as f: f.write(user)with open("pwd.txt",'w') as f: f.write(pwd)##### main script ###### load all pwdsf2 = open("pwd.txt", "r")lstpwd = f2.readlines()f1 = open("user.txt", "r")threads = []def brute():    for letter in f1.readlines():        print ("\n[+]First Value: {}".format(letter.strip()))        for second_letter in lstpwd:            print ("[++]Second Value: {}".format(second_letter.strip()))            threads.append(threading.Thread(target=runner, args=(letter,second_letter,)))    for thread in threads:        thread.start()    for thread in threads:        thread.join()    def runner(word1,word2):    print("[+]I am just a worker class: {0}:{1}".format(word1.strip(),word2.strip()))    brute()输出[+]First Value: user1[++]Second Value: pwd1[++]Second Value: pwd2[++]Second Value: pwd3.......    [+]First Value: user2[++]Second Value: pwd1[++]Second Value: pwd2[++]Second Value: pwd3.......[+]I am just a worker class: user1:pwd1[+]I am just a worker class: user1:pwd2[+]I am just a worker class: user1:pwd3.......[+]I am just a worker class: user2:pwd1[+]I am just a worker class: user2:pwd2[+]I am just a worker class: user2:pwd3.......
