服務器
socket
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)AF_INET指定使用IPv4協議，如果要用更先進的IPv6，就指定為AF_INET6。SOCK_STREAM指定使用面向流的TCP協議，這樣，一個Socket對象就創建成功，但是還沒有建立連接。
bind
server_socket.bind(("127.0.0.1", 8080))服務器可能有多塊網卡，可以綁定到某一塊網卡的IP地址上，也可以用0.0.0.0綁定到所有的網絡地址，還可以用127.0.0.1綁定到本機地址。127.0.0.1是一個特殊的IP地址，表示本機地址，如果綁定到這個地址，客戶端必須同時在本機運行才能連接，也就是說，外部的計算機無法連接進來。
listen
server_socket.listen(128)
調用listen()方法開始監聽端口，傳入的參數指定等待連接的最大數量
accept
等待并返回一個客戶端的連接，采用多進程來處理要做的事情
while True:client_socket, client_address = server_socket.accept()handle_client_process = Process(target=handle_client, args=(client_socket,))handle_client_process.start()client_socket.close()
