Introduction to Redis:First, IntroductionRedis is an open source, Key-value database that is written in C and that supports network interaction and can be persisted based on memory. Redis source code is very simple, as long as there is time to see rectification C language, to see the source of Redis can read 50-60%. The current largest cluster of Redis should be

Web Crawl Web sites use HTML descriptions, which means that each Web page is a structured document. Sometimes it is useful to get data from it while maintaining its structure. Web sites do not always provide their data in an easy-to-handle format, such as CSV or JSON. This is the time for the web to crawl out. Web crawling is the practice of using a computer program to collect and organize Web page data into the desired format while preserving its structure. lxml and requestslxml (http://lxml.

Python functions and modules, Python function modulesIntroduction Function concepts also exist in python. Standard functions can be called built-in functions, which can be called directly by function names. However, some other built-in functions cannot be called directly through the function name, such as the floor function (rounded down). Then we need to use the module; this article mainly introduces math and cmath. Python version: 3.4.4 Built-in fu

, it exists in the lifetime of the program, and the data value in the class instance exists in the object's lifetime, and it is created with the object's creation, Disappears with the object's revocation. Finally, when a variable is declared public in a standard module, it is visible anywhere in the project, while the public variable in the class module is accessible only if the object variable contains a reference to a class of instances.In general, classes are used in the following two situati

The examples in this article describe the Python creation module and the method of module import. Share to everyone for your reference. The specific analysis is as follows: The Python Learning manual reads: Define modules, just use a text editor, enter some Python code into the text, and then save with a. py suffix name, any such file would be considered a Python module. For example, the following code is entered into a file and can be viewed as a

Since some PDF files need to be downloaded from a Web page, there are hundreds of PDF files to download, so it is not possible to download them manually. Python has the relevant modules, so I wrote a program to download the PDF file, and by the way, I was familiar with Python's Urllib module and ULRLLIB2 module. 1, the problem description A PDF file containing hundreds of papers from the http://www.cvpapers.com/cvpr2014.html is required, as shown in

Assume that the two redis servers have ip addresses 192.168.1.101 and 192.168.1.103 respectively. How can I access redis on redis 101 through redis-cli on redis 103? Before remotely connecting to redis 103, let's talk about severa

. When I first started reading the redis source code, I used this method: first starting from a separate data structure module, and then transitioning to a high-level functional module. Start with the function: Quickly locate the specific implementation of a function through the file name (Module name) and function name, and then track the entire implementation process to learn how this function is implemented. This method is used when I read a bl
