python socket programming

Socket is a way of inter-process communication, and other processes of communication between the main difference is: to achieve inter-process communication between different hosts, the network of a variety of services are based on the socket to complete the communication, to solve the network of two host communication problems, the first to uniquely identify the process, In TCP/IP network protocol, it is th

Python Socket network programmingSocket is a method of inter-process communication. It communicates with other processes mainly in different ways: it can implement inter-process communication between different hosts, most of our various services on the network communicate based on sockets, such as Browsing webpages, chatting via QQ, sending and receiving emails, etc. To solve the process communication probl

Python provides two levels of access to network services:1.Socket: The low-level network service supports the basic socket, which provides the standard BSD Sockets API, which can access all methods of the underlying operating system socket interface.2.SocketServer: High-level Network Service Module Socketserver, which

(also known as link layer) Data Link Layer Physical Layer The socket to be introduced today is located between the application layer and the transport layer.Example: And for TCP, to figure out the transmission of data streams, three handshakes and four waves are something that must be known. Python network programming has said so much

family based on network typeSocket family name: af_inet(There are also af_inet6 used for IPv6 and some other address families, but they are either used only on a platform, or have been discarded, or are rarely used, or are not implemented at all, and Af_inet is the most widely used one in all address families, Python supports a variety of address families, but since we only care about network programming,

This usage is for creating files or directories, creating a success without output information

Introduction to basic socket programming in Python, pythonsocket In network communication, sockets are almost everywhere. It can be seen as an intermediate software abstraction layer for communications between the application layer and the TCP/IP protocol cluster. It is an interface for two applications to communicate with each other, in addition, the complex TCP

') S.close () Then we open two command-line windows, one running the server program and the other running the client program to see the effect. It should be noted that the client program is finished running, and the server program will run forever, you must press CTRL + C to exit the program.
