# 获取本地主机名

# 绑定端口
serversocket.bind((host, port))

# 设置最大连接数，超过后排队

客户端

# 文件名：client.py 
# 导入socket、sys模块

import socket
import sys

# 创建socket对象
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

#获取本地主机名
host = socket.gethostname()

#设置端口
port = 9999

# 连接服务，指定主机和端口
s.connect((host,port))

# 接收小鱼1024字节的数据
msg = s.recv(1024)

s.close()

print(msg.decode('utf-8'))
