I. WedgeNow that you've learned to write Python code, if you've written two Python files a.py and b.py and run them separately, you'll find that the two Python files work well. But what do you do if you want to pass a data between the two programs?This problem can be solved with your knowledge now, we can create a file, write the content that a.py want to pass to

Brief introductionAsyncio is an asynchronous I/O framework that follows the Python standard library. In this article, I'll introduce uvloop: a complete alternative to the Asyncio event loop. Uvloop is written in Cython, based on LIBUV.Uvloop makes Asyncio faster. In fact, it's at least twice times faster than nodejs,gevent, and any other Python async framework. Uvloop Asyncio Performance-based testing is cl

Synchronous, asynchronous, blocking, and non-blocking. when these network I/O terms are combined, it will inevitably confuse programming beginners, here we will summarize the Python instances of the network I/O model and select model for you: Network I/O modelIf there are too many people, there will be problems. When t

Urllib2 is a Python component used to obtain URLs (UniformResourceLocators. He provides a very simple interface in the form of the urlopen function. next we will use examples to explain his usage. this is capable of obtaining URLs using different protocols, it also provides a complex interface to handle general situations, such as basic verification, cookies, proxies, and others. They are provided through handlers and openers objects. Urllib2 supports

For acquisition, registration or agent, if the server public network IP can automatically switch, then there may be a lot less trouble. Recently, bloggers have implemented this small function using the Aliyun API. The implementation of the steps are relatively simple, first need to apply for Aliyun API key. Then apply for VPC proprietary network, ordinary classic ECS host can not mount elastic IP, in the ne

This article mainly introduces the Getting Started Tutorial on network programming using threads in Python. This article is from the technical documentation on the IBM official website. For more information, see Introduction For Python, there is no lack of concurrency options. its standard library includes support for threads, processes, and asynchronous I/O. In

Socket is the network connection endpoint. I. Introduction to Network Knowledge Socket is the network connection endpoint. For example, when your Web browser requests the homepage of www.bitsCN.com, your Web browser creates a socket and commands it to connect to the Web server host of www.bitsCN.com, the Web server also listens to requests from a socket. Both en

implement client and server sockets. To build a simple server with TCP and streaming sockets in Python, you need to use the socket module. Using the functions and class definitions contained in the module, you can generate programs that communicate over the network. In general, it takes six steps to establish a server connection.The 1th step is to create the socket object. Call the socket constructor.Socke

I. Overview of DB-API Python supports a number of different databases. Because different seller servers result in different network protocols for database communication. In earlier versions of Python, each database had its own Python module, all of which worked in different ways and provided different functions. This m

Before starting the Python network programming, the first thing to know about sockets, sockets is a computer network data structure. There are two types of sockets, namely, file-based and network-based, the former such as Af_unix, the latter such as Af_inet, Af_netlink. The socket port, like the telephone number, is th

This article illustrates how Python implements network port forwarding and redirection. Share to everyone for your reference, specific as follows: Task A network port needs to be forwarded to another host (forwarding), but may be a different port (redirecting). "Solution" Two classes that use the threading and socket modules will be able to complete the port

Overview This demo is very suitable for beginners AI and deep learning students, from the most basic knowledge, as long as there is a little bit of advanced mathematics, statistics, matrix of relevant knowledge, I believe you can see clearly. The program is written without the use of any third-party deep Learning Library, starting at the bottom. First, this paper introduces what is neural network, the characteristics of neural
