练习题 多线程实现sock编程

server端：

from multiprocessing import Process
from socket import *
def talk(conn):
    while True:
        try:
            data=conn.recv(1024)
            if not data:
                break
            conn.send(data.upper())
        except ConnectionResetError:
            break
    conn.close()
def server(ip,port):
    server=socket(AF_INET,SOCK_STREAM)
    server.setsockopt(SOL_SOCKET,SO_REUSEADDR,1)
    server.bind((ip,port))
    server.listen(5)
    while True:
        conn,addr=server.accept()
        p=Process(target=talk,args=(conn,))
        p.start()
    server.close()
if __name__ == "__main__":
    server("127.0.0.1",8080)

client端：

from socket import *
client=socket(AF_INET,SOCK_STREAM)
client.connect(("127.0.0.1",8080))
while True:
    msg=input(">>")
    if not msg:continue
    client.send(msg.encode("utf-8"))
    data=client.recv(1024)
    print(data.decode("utf-8"))

 问题：

客户端一直连接，服务端一直起进程处理，数量有限
