写一个基于TCP协议套接字，服务端实现接收客户端的连接并发。

多线程

#客户端
import socket

client=socket.socket()
client.connect(('127.0.0.1',8888))
# def c():
while True:
    s = input('输入：')
    client.send(s.encode('utf-8'))
    data=client.recv(1024).decode('utf-8')
    print(data)
client.close()
#服务端
import socket
from threading import Thread
def s(conn):
    while True:
        try:
            data=conn.recv(1024).decode('utf-8')
            print(data)
            conn.send(data.encode('utf-8'))
        except Exception as e:
            print(e)
            break
    conn.close()

if __name__ == '__main__':
    # while True:
    server = socket.socket()
    server.bind(('127.0.0.1', 8888))
    server.listen()
    while True:
        conn,addr=server.accept()
        t=Thread(target=s,args=(conn,))
        t.start()

多进程

#客户端
import socket

client=socket.socket()
client.connect(('127.0.0.1',9999))
while True:
    data=input('客户端输入：')
    client.send(data.encode('utf-8'))
    msg=client.recv(1024).decode('utf-8')
    print(msg)
#服务端
import socket
from multiprocessing import Process
def s(conn):
    while True:
        try:
            data=conn.recv(1024).decode('utf-8')
            print(data)
            conn.send(data.encode('utf-8'))
        except Exception as e:
            print(e)
            break
    conn.close()
if __name__ == '__main__':
    server=socket.socket()
    server.bind(('127.0.0.1',9999))
    server.listen()
    while True:
        conn,addr=server.accept()
        t=Process(target=s,args=(conn,))
        t.start()
