Python 套接字总是关闭

Question

我有一个使用TCP和UDP套接字的套接字客户端，即使我没有关闭套接字连接，但是当我执行完脚本时，连接断开了我怎样才能保持连接始终打开，
这是代码：

import socket
import sys
import time

HOST = "163.173.96.12"  # Standard loopback interface address (localhost)
PORT = 32000        # Port to listen on TCP/IP
PORT1 = 32001       # Port to listen on UDP/IP

#TCP/IP
try:
    client_tcp = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    tcp_server_address = (HOST, PORT)
except:
    print("Cannot find server TCP")
finally:
    client_tcp.connect(tcp_server_address)
    print('Connection TCP sucessful')

#UDP/IP
try:
    client_udp = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) 
    udp_server_address = (HOST, PORT1)
except:
    print("Cannot find server UDP")
finally:
    client_udp.connect(udp_server_address)
    print('Connection UDP sucessful')

try:
    for i in range(1,11):
        texte = "PING\n"
        client_tcp.send(texte.encode())
        data=client_tcp.recv(1024).decode('utf-8')
        print("Received ", str(data))
except:
    print("error occur")    
finally: 
    #client_tcp.close()
    #client_udp.close()
    print('Closed')

谢谢

套接字已关闭，因为当您到达程序末尾时，进程终止，然后操作系统看到进程未使用的资源（套接字），因此将其删除。

要防止这种情况，您需要防止进程死亡。所以在程序末尾添加其中之一，它不会关闭，保持套接字打开：

input("Press enter to close")

from threading import Event

Event().wait()

Python 套接字总是关闭

Python socket always close
