Let's discuss the decorator today. The decorator is a well-known design model and is often used in scenarios with cut-plane requirements. It is more classic in terms of log insertion, performance testing, and transaction processing. The decorator is an excellent design for solving such p

SocketSockets 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. Socket is an implementation of this pattern, the socket is a special kind of file, s

, but it also has a wide range of "native" libraries to handle large-scale data (especially Twitter's algebird and Summingbird). It also includes an easy-to-use REPL for interactive development and analysis, just as with Python and R.I personally love Scala because it includes many practical programming features, such as pattern matching, and is considered much simpler than standard Java. However, using Sca

static data . They represent that the data is bound to the class object to which they belong and does not depend on any class instance. If you are a Java or C + + programmer, this type of data is equivalent to adding the static keyword before a variable declaration.Static members are typically used only to track values associated with a class. class Attri (): " Class attribute Test " if __name__ ' __main__ ' : Print (attri.arrtitest) D:\Python
From C # To Python -- 3 function and function programming,
In C #, there is no independent function. Only the class (dynamic or static) method is used. It refers to the member used to execute computing or other behaviors in the class. In Python, you can use a method similar to C # To define the dynamic or static member methods of a class, because it supports full
