Python 局域网存活主机扫描，让map函数传入多个参数，网页端口扫描

 局域网存活主机扫描

import re
from functools import  partial
from multiprocessing.dummy import Pool as ThreadPool
import time
import os 

def ping(num,ip):
    a = os.popen('ping '+ip+str(num)).read()
    text=re.findall("TTL=(.*?)\n",a)
    if text==[]:
        s="no"
    else:
        s=text[0]
    print(ip+str(num)+"  "+s)
    os.close

if __name__=="__main__":
    t=[]
    ip="172.19.20."
    for i in range(0,256):
        t.append(i)
    pool=ThreadPool(512)
    pool.map(partial(ping,ip=ip),t)#t 对应第一个参数
    pool.close()
    pool.join()

 url端口扫描

import requests
import re
import urllib
from urllib.request import urlopen
from functools import  partial
from multiprocessing.dummy import Pool as ThreadPool

def pt(port,url):
    url=url+":"+str(port)
    try:
        req=requests.get(url)
    except:
        req="no"
    print(req,i)

if __name__=="__main__":
    t=[]
    url="http://127.0.0.1"
    for i in range(0,256):
        t.append(i)
    pool=ThreadPool(512)
    pool.map(partial(pt,url=url),t)#t 对应第一个参数
    pool.close()
    pool.join()
