python中的文件迭代问题[重复]

Question

我有一个分配，其中我有两个文件，即“user.txt”，“pwd.txt”现在我想基本上迭代这些文件的每个值，即“John”，所有值都在“pwd.txt”中。 txt”，然后是“user.txt”中的另一个值，所有值都是“pwd.txt”。

这里我要实现线程。

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))

输出如下

[+]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打印所有用户值以及密码文件中的所有密码。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 testing
user = "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 pwds
f2 = 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
.......
