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

Initial knowledge of socket programmingFirst, prefaceThe socket is based on the programming model of the C\S architecture (client \ Server), which is present in Python as a socket module.A socket is an intermediate software abstraction layer that the application layer communicates with the TCP/IP protocol family, which is a set of interfaces. In design mode, thesocket is actually a façade mode, it is the co

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

First, what is a Python objectIn Python, a value of any type constructed is an object. For example, a value of an integer type, a string, a list, and so on, can be considered as objects.All objects are divided into three parts:(1) identity. Each object has an ID that identifies itself. Available built-in function ID () view(2) type. Available type () view(3) value. Objects are used to hold data, and the mos
