-------------------
运行 python input_test.py -H 127.0.0.1 -P 80,443

报错： TypeError：an integer is required

参考技术A

运行不出错，但没有任何东西，我用的3.x版本

追问

try:
s = socket(AF_INET,SOCK_STREAM)
s.connect((host,port))
lock.acquire()
openNum+=1
print('[+] %d open' % port)
lock.release()
s.close()
except:
pass
这个try 去掉就有报错信息了 已经找到了 问题了

参考技术B 2.7版本没问题，帮不上了。。 参考技术C 因该是你在传入参数的时候有一个参数类型搞错了。不知道具体出错在哪一行？
