This paper mainly introduces the Python implementation of asynchronous agent crawler and agent Pool of knowledge, has a good reference value, following the small series to see it together Use Python Asyncio to implement an asynchronous agent pool, according to the Rules crawl agent site free agent, after verifying that it is valid in Redis, regularly expand the number of agents and verify the effectiveness

SELENIUM2 python automated testing using the AutoIt tool for local file uploadsI'm learning based onPythonlanguage ofselenium2During the automated test method, when a test involving a local upload file is found,selenium2when locating localwindowThere is limited capacity on the object (element) of the window. When the upload button is using theinputlabel, you can

Because the work needs to be in a large number of logs to extract some of the corresponding fixed characters, if simply by manual extraction, data volume, labor, and then naturally think of using Python to do a corresponding extraction tool, instead of manual extraction of the complex, involving Chinese characters, regular expression bad match, but not can not be achieved, After this optimization is again.

This section briefly introduces how to load a template using the Python Django framework. Generally, you store templates in the file system as files, but you can also use custom template loaders to load templates from other sources. Django has two ways to load templates Django. template. loader. get_template (template_name): get_template returns a compiled Template (a template object) based on the given

Naive Bayesian algorithm is simple and efficient, and it is one of the first ways to deal with classification problems. With this tutorial, you'll learn the fundamentals of naive Bayesian algorithms and the step-by-step implementation of the Python version. Update: View subsequent articles on naive Bayesian use tips "Better Naive bayes:12 tips to get the Most from the Naive Bayes algorithm"Naive Bayes classifier, Matt Buck retains part of the copyri

This section briefly introduces how to parse and modify XML documents using Python. ProblemYou want to read an XML document, modify it the most, and write the result back to the XML document. SolutionThe xml. etree. ElementTree module can easily process these tasks. The first step is to parse this document in the usual way. For example, suppose you have a documen

The previous article briefly introduced the concept and use of the descriptor (descriptor) in Python, with the intention of the classmate estimating that the skill has been get√. This article gives a case once again by using a descriptor scenario, making it easier for students who don't understand the situation to understand. Let's talk about decorator. These two words are indeed somewhat similar, and are

other tasks, the program first to execute other code, wait until the network communication has results, the system will notify you, and then go back to the place where the interruption just. The specific code below, I will elaborate, probably summed up the following code involved in the technology 1. Page parsing, Webshell password automatic post, it is necessary to address the problem of page parsing, that is, how to find the form in the page of t

feature library, Then compare the verification code with the feature library. This is more complicated, a blog post is not finished, here will not start, specific practices please make a study of the relevant textbooks.-3. In fact some of the verification code is still very weak, here is not named, anyway, I have 2 of the method to extract the very high accuracy of the verification code, so 2 is actually feasible.-6. SummaryBasically I have encountered all the situation, with the above methods
