Recently, just after the internship, very much like the experimental building, but their own direction is still not sure, I think the space is very large, although already a senior person, think of others are busy to buy professional clothes, buy high-heeled shoes interview, learn makeup, look at themselves, instead began to slowly focus on sports, diet and skin care, haha, The programmer is Jiangzi, the body is the capital of revolution. Now the direction is at least determined, the data analys

14.1.1 Socket ModuleIn network programming, a basic component of Lourdes is the socket. Sockets are primarily information channels between two programs.Sockets consist of two: Server sockets and Client sockets. After creating a server socket, let it wait for the connection. So it listens at a network address.A socket is an instance of the socket class in a socket

there is a "distributed System" this book, if you are blocking calls, you will always put yourself "hang" until the book has no results, if the non-blocking call, you don't care if the boss has told you, you have to play the first side, Of course, you'll have to check the boss for a few minutes occasionally.Here the blocking is independent of the non-blocking and whether synchronous asynchronous. It has nothing to do with how the boss responds to your results.2. Use forkingmixin in the socket s

This article illustrates the implementation of file download for Python network programming. Share to everyone for your reference. Specifically as follows: It's so easy to understand the HTTP and FTP downloads that it offers, because it's more and more like python. 1, the corresponding module The Ftplib module defin

This article mainly introduces the tutorial on UDP network programming in Python. UDP programming is the basic knowledge of Python network programming. the sample code is based on Pytho

ViewInsert two data into the database beforehandbelow we take the data out of the database and return it to the HTTP request. In blog/views.py, add a view. For the corresponding request, we will read all the records from the database and then return to the client:#-*-Coding:utf-8-*-from django.http import httpresponsefrom blog.models import testdef outstr (Request): blog_list = Test.objects.all () blog_str = map (str, blog_list) return HttpResponse ("In order for the HTTP request to f

Python network programming-epoll of IO multiplexing What is epoll? What is epoll? In linux network programming, select is used for event triggering for a long time. In the new linux kernel, there is a mechanism to replace it, that is, epoll. Of course, this is not only avail

Python Pycurl Network Programming example In the use of urllib often die, debug before, is not set timing out so timeout will die.Pycurl is a Curl Python library, although some curl features are not implemented, but they are still strong.Curl is a very powerful tool,Google uses it internally to debug the GDATA API.

[Python network programming] Design and Implementation of daemon background tasks In B/S-based applications, you often need to run tasks in the background, such as sending emails. In some projects, such as firewalls and WAF, the front-end only displays content and various parameter configurations, and the background daemon process is a major concern. Therefore, y

Previously also learned the socket programming, this time want to systematically study the use of Python network programming. Do this, for testing progress, also leave notes and footprints for the follow-up. Socket common functions get host name and host address Socket.gethostname () Socket.gethostbyname () Import Soc

are rarely used, or are not implemented at all, in all address families, Af_inet is the most widely used one, Python supports a variety of address families, but since we only care about network programming, most of the time I only use af_inet.5.TCP Protocol and UDP protocolTCP(transmission Control Protocol) Reliable, connection-oriented protocol (eg: call), low

"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, some of the socket function is the operation of it (read/write Io, open, close)The difference between a socket and file: The file module is "open", "Read and write" "Close" for a specified document The socket module is "open", "Read and write" "Off" for server-side and client sockets TCP Communication, the fi
