Python network programming-socket, python Network Programming1. TCP/IP To understand socket, you must first familiarize yourself with the TCP/IP Protocol family, namely, the Transport Control Protocol/internetprotocol, defines the criteria for how a host connects to the Internet and how data is transmitted between them

Prior to implementing the Java version of the TCP and UDP socket programming example, so decided to combine Python learning to do a python version of the socket programming experiment.The process is as follows:1.

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

On a sunny afternoon, think of the recent start from writing Java to writing Python, and then open your computer to experience the difference between Python and Java ~Remember when I was a sophomore, that time to learn Java, the most interesting is the Java book the last chapter of the socket socket that part, the firs

Python has the widest range of web aspects to apply. Therefore, the socket is very important.To use the socket, you must introduce a socket module, so write to the beginning of the Python script1 Import SocketLearn the socket is k

: connection-oriented and no-connection. Connection-oriented: The TCP protocol used is to establish a reliable connection before the data is transmitted, and then the data is transmitted in the form of a byte stream. So that the data is reliable, non-repeatable, and orderly. Because it is a byte stream, there is no data boundary, it can split a piece of data into multiple parts, which facilitates the efficiency of transmission. No connection: Use of the UDP protocol, the transmissio

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, most of the time I use af_inet only)
