python3 port scanning script

Ah Long time did not write the code, thinking multithreaded what are almost forgotten 
on the following matter,

#coding=utf-8
import socket,threading
from socket import *

def tcp_connect(ip,port):
    tcpsock=socket(AF_INET,SOCK_STREAM)
    tcpsock.settimeout(0.5)
    try:
        result=tcpsock.connect_ex((ip,port))
        if(result==0):
            print ("%s:%s 开启" % (ip, port))
        else:
            #print ("%s:%s 关闭" % (ip, port))
            pass
        tcpsock.close()
    except socket.error as e:
        print ("[!]错误",e)

def url_ip(url):
    if('http://' in url or 'https://' in url):
        url=url[url.find('://')+3:]
        targetip = socket.getaddrinfo(url, 'http')[0][4][0]
        print (targetip)
        port_scan(targetip)
    else:
        targetip Socket.getaddrinfo = (URL, ' HTTP ' ) [0] [. 4 ] [0]
         Print (TargetIP) 
        port_scan (TargetIP) 

DEF port_scan (IP):
     for I in Range (200 is ): 
        the tcp_connect (IP, I) 

DEF main ():
     Print  " ------------- " 
    Print  " . 1: IP port scan " 
    Print  " 2: scan port URL " 
    Print  " ------------- " 
    Q = the raw_input ( " select: " )
     IF (int (Q). 1 ==):
        w=raw_input("ip=")
        t=threading.Thread(target=port_scan,args=(w,))
        t.start()
    else:
        e=raw_input("url=")
        url_ip(e)
main()

    for t in threads:

    print('[*] The scan is complete!')
    print('[*] A total of %d open port ' % (openNum))
