python尝试windows在用端口

安装 func_timeout 作用：超时强制终止函数。

import pandas as pd
from func_timeout import func_set_timeout, FunctionTimedOut
import socket



def try_port(ip='10.129.23.203',port='8888'):
    try:    
        @func_set_timeout(1)
        def isInuse(ip, port):
            s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            flag=True
            try:
                s.connect((ip, int(port)))
                s.shutdown(1)
                print(port,'ok')
                flag=True
            except:
                print(port,'wrong1')
                flag=False
            return flag
        flag = isInuse(ip, port)
    except:
        print(port,'wrong2')
        flag=False
    return flag



try_port(ip='127.0.0.1',port='8888')
try_port(ip='10.129.23.203',port='8888')





list_01 = []
for i in range(100000):
    flag = try_port(ip='10.129.23.203',port=i)
    if flag:
        list_01.append(i)
