The purpose of the Pykka project is to provide Python with an easy-to-use, concurrency-operational abstraction layer using Actor mode.Pykka provides the Actor API, which contains two different implementations: Threadingactor is built in the Python standard Library ' sthreadingandQueuemodules, and have no D Ependencies outside Python itself.

DOM4J creates a tree object model in memory for an XML document. It provides a powerful set of Easy-to-use APIs that process, manipulate, or traverse XML files through XPath and XSLT, as well as the integration of Sax, JAXP, and Dom. To provide a highly configurable implementation strategy, DOM4J is based on interface design. Just provide a documentfactory implementation, and you can create your own XML tree implementation. This design makes it very easy to reuse dom4j code when extending dom4j

meaning of these methods, see machine learning textbook. One more useful function is train_test_split.function: Train data and test data are randomly selected from the sample. The invocation form is:X_train, X_test, y_train, y_test = Cross_validation.train_test_split (Train_data, Train_target, test_size=0.4, random_state=0)Test_size is a sample-to-account ratio. If it is an integer, it is the number of samples. Random_state are the seeds of random numbers. Different seeds can result in differen

Reflections contains a lot of scanner, that is, the scanner, call the corresponding method needs to have a configuration corresponding to the scanner, or the program will throw an exception.Scanner structure:When used, we mainly use the reflections class to invoke.Reflections a portion of the scanner is configured by default,However, in the actual use of the need to add a lot of scanners, can be based on the exceptions thrown by the program to add a corresponding scanHow to use:New New New New N

I have been using Swing since the 90 's. The reason I love Swing is that it can fulfill all your ideas. For me, this is the wonderful thing about developing software: Being able to realize what you think on the screen. With the Swing API, you can easily use a wide variety of applications, from drag-and-drop tools to arcade games, omnipotent. Then, the advent of primitive frameworks such as server-side Java and Struts has allowed software development to go back to the the 1960s level, and they c

Objective The MVC pattern is the classic pattern in the design pattern, which can effectively separate the data layer, the presentation layer, and the business logic layer. WEB2.0 technology is widely used in the display layer of WEB application because of its good user experience. However, in the traditional web development, the display layer and the business logic layer of the code a large number of coupling, so that the application of the scalability seriously reduced, while the page layer c
