本文例項為大家分享了python 3.6.7埠掃描器的具體程式碼，供大家參考，具體內容如下

環境：python 3.6.7

# -*- coding: utf-8 -*-
import socket
import threading
import argparse

lock = threading.Lock()
openNum = 0
threads = []

def portscan(ip,port):
 global openNum
 try:
 s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
 s.connect((ip,port))
 lock.acquire()
 openNum = openNum + 1
 print('[+] %d open' %port)
 lock.release()
 s.close()
 
 except:
 pass
 
def main():
 parse = argparse.ArgumentParser()
 parse.add_argument('-H',dest = 'ip',type = str)
 args = parse.parse_args()
 ip = args.ip
 socket.setdefaulttimeout(3)
 
 for port in range(1,1024):
 t = threading.Thread(target = portscan,args = (ip,port))
 threads.append(t)
 t.start()
 
 for t in threads:
 t.join()
 
 print('[*] The host:%s scan is complete!' %(ip))
 print('[*] A total of %d open port ' %(openNum))
 
if __name__ == '__main__':
 main()
