established. While the server-side socket continues to be in the listening state , it continues to receive connection requests from other client sockets. One of the basic components in network programming is the socket (socket). Sockets are mainly "information channels" between two programs. Programs may be distributed across different computers (over a network connection), sending information to each oth

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/IP protocol details are hidden behind the in

File-like object to read and write to the Socket. Handle (): Process the Request. Resolves incoming requests, processes data, and sends a response. Nothing is done by Default. Common Variables: Self.request,self.client_address,self.server. Finish (): Environment Cleanup. Nothing is done by default, and if Setup produces an exception, the finish is not Executed. typically, you only need to overload Handle. The type of self.request differs

following methods can be overloaded: Setup (): Prepares request processing. By default, nothing is done, and Streamrequesthandler creates a file-like object to read and write to the socket. Handle (): Process the request. Resolves incoming requests, processes data, and sends a response. Nothing is done by default. Common variables: Self.request,self.client_address,self.server. Finish (): Environment cleanup. Nothing is done by defaul

First of all, the HTTP exception handling problem.When Urlopen cannot handle a response, a urlerror is generated.However, the usual Python APIs such as Valueerror,typeerror can also be generated.Httperror is a subclass of Urlerror that is typically generated in a specific HTTP URL. 1.URLErrorTypically, urlerror occurs without a network connection (not routed to a specific server), or if the server does not exist.In this case, the exception also has t

Python sockets basic Use socketSockets are also commonly referred to as "sockets," which describe IP addresses and ports, and applications usually make requests to the network through "sockets" or respond to network requests, which can be considered a data structure and interface for a computer network. It is the found

Sockets are also commonly referred to as "sockets," which describe IP addresses and ports, and are a handle to a chain of communication, where applications usually make requests to the network through "sockets" or respond to network requests.Sockets originate from UNIX, and one of the basic philosophies of unix/linux is "Everything is file", and the file is operated with "open" "Read and Write" "Off" mode.

1.Python is very good at code readability, in general, it is recommended to add a space between the operators and commas , adding a blank line between code blocks of different functions .2. Everything in Python is object , in addition to the commonly used built-in objects (shown in table 1 below), there are a large number of standard library objects and extension library objects, the standard library is the

ObjectiveThe so-called Web crawl, is the URL address specified in the network resources from the network stream read out, save to Local. There are many libraries in python that can be used to crawl Web pages, so let's learn urllib first.Note: This blog development environment is Python3UrlopenLet's start with a piece of code:# urllib_urlopen.py# 导入urllib.requestimport urllib.request# 向指定的url发送请求，并返回服务器响应的类文件对象response = urllib.request.urlopen("http://
