This article mainly introduces python how to achieve socket programming server and client, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

1. The server can be a program, a computer, or a device dedicated to managing network resources. Use the socket.socket () method to create server-side socket characters.

The server can be on the same device or computer, connect to other devices and computers locally, or even connect remotely. There are various types of servers, such as database servers, network servers, print servers and so on.

The server usually uses methods such as socket.socket (), socket.bind (), socket.listen (), and so on, to establish a connection and bind to the client.

The first necessary condition for setting up sockets is to import the socket module.

Import sockets=socket.socket (socket.AF_INET, socket.SOCK_STREAM) s.bind ((socket.gethostname (), 1234)) # port number can be anything between 0-65535 (we usually specify non-previleged ports which are > 1023) s.listen (5) while True: clt,adr=s.accept () print (f "Connection to {adr} established") # f string is literal string prefixed with f which # contains python expressions inside braces clt.send (bytes ("Socket Programming in Python") "utf-8")) # to send info to clientsocket

2. A client is a computer or software that receives information or services from a server. Import the socket module to create the socket.

In the client server module, the client requests services from the server. The best examples are Web browsers, such as GoogleChrome,Firefox and so on. These Web browsers require users to indicate the required web pages and services to the Web server. Other examples include online games, online chat and so on.

To create a connection between the client and the server, you need to use connect () through the specified method (host and port).

Note: use gethostname when the client and server are on the same computer.

Import sockets=socket.socket (socket.AF_INET, socket.SOCK_STREAM) s.connect ((socket.gethostname (), 2346)) msg=s.recv (1024) print (msg.decode ("utf-8")) Thank you for reading this article carefully. I hope the article "how python implements the server and client of socket programming" shared by the editor will be helpful to you. At the same time, I hope you will support me and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
