python frameworks

Python is a dynamic, object-oriented language. It was originally designed as an object-oriented language, and later added some more advanced features. In addition to the language itself, the Python standard library is well worth praising, and Python even has its own servers. In other ways, Python has plenty of free dat

How about pylons? How about pylons? Reply: for beginners, step by step is the most important. I recommend learning Flask (Welcome | Flask (A Python Microframework) ) Flask is very light and can be used to develop a simple website at a very low cost. It is very suitable for beginners to learn. After learning about the Flask framework, you can consider using plug-ins. For example, you can use WTForm + Flask-WTForm to verify form data and use SQLAlchemy

criticized orm and template of Django, if you want to replace it with sqlalchemy and Mako, it is almost impossible. Even if you barely use it, it will make you very awkward. To talk about the world's major events, we must combine them for a long time. In the Warring States Period of Python web framework, Django was almost the only one. However, if other frameworks are combined vertically, they may not co

-performance single-thread non-blocking asynchronous model, which is an exception. Nginx is a server dominated by static content and front-end proxy. Various Python frameworks are used to implement dynamic logic. Nginx listens to client connections, directly responds to static requests (images, css, js, etc.), and then sends dynamic requests through FastCGI (web. py) or the proxy (Tornado) is forwarded to

The small series collects some of the more efficient Python crawler frameworks. Share to everyone.1.ScrapyScrapy is an application framework written to crawl Web site data and extract structural data. Can be applied in a series of programs including data mining, information processing, or storing historical data. With this framework, you can easily climb down data such as Amazon commodity information.

This article mainly introduces the introduction to the ORM framework in Python, the sample code is based on the python2.x version, the need for friends can refer to the With the DB module, it is convenient to manipulate the database to write SQL directly. However, we still lack ORM. If you have ORM, you can get the user object in a statement like this: ? 1 user = User.get (' 123 ') Instead of writing SQL and then convertin

the way, you can drop simple requests directly. Another logic that focuses on applications. Of course, nginx can do more than this, and for the convenience of development, web. py and other frameworks are built into a simple web server. As for tornado, there are both web application frameworks and web servers, and this server uses a high-performance single-thread non-blocking asynchronous model, which is

. PIL is very powerful, but the API is very easy to use pip3 install PillowUse of third-party modulesManipulating imagesThe following is the most common example code for image scaling operationsfrom PIL import Image# 打开一个jpg图像文件，注意是当前路径:im = Image.open(‘titan.jpg‘)# 获得图像尺寸w, h = im.sizeprint(‘image size: %sx%s‘ % (w, h))# 缩放到50%:im.thumbnail((w//2, h//2))print(‘image to: %sx%s‘ % (w//2, h//2))# 把缩放后的图像用jpeg格式保存:im.save(‘jun.jpg‘, ‘jpeg‘)Other features such as slices, rotations, filters,

content and front-end agent-based server, Python's various frameworks for the implementation of dynamic logic. Common collocation is the Nginx listening client connection, directly respond to static requests (picture, CSS, JS, etc.), and then transfer the dynamic request through FastCGI (web.py) or proxy (Tornado) to the backend server for processing. Nginx itself is written in C, the code is highly efficient, supports dynamic balance, and is more s

spoofing submission requests. The POST method submits a table that must have this label.② Create a new search2.py file and use the Search_post function to process the POST request:[Python] View plain copyFrom django.shortcuts Import RenderFrom django.views.decorators import csrf# Receive POST request datadef search_post (Request):CTX ={}If request.

Just as glory belongs to Greece, greatness belongs to Rome. The elegant combination of Python and WSGI design makes the web framework interface un

The former is more mainstream and more stable.However, Apache's MOD_WSGI configuration is cumbersome and memory consumption is large.The 4.CherryPy----is a Python-based object-oriented HTTP framework. Using CherryPy to develop Web application is very easy. But CherryPy doesn't provide a php-like templating language mechanism. All it does is to connect the Web server to your

Quantitative investment strategy: several common Python back-testing frameworks (libraries)Original address: http://blog.csdn.net/lawme/article/details/51454237This article is reproduced in the article. This time in the study of quantitative strategy direction, studied zipline for some time, but the follow-up found he only support U.S. stocks, collect quantitative strategy articles, reproduced in the blog.T

Other gains from sd2c come from web applications. One is Dong Jing's Gae lecture, and the other is Qian Hongwu's lecture on large-scale Web applications. Qian Hongwu has a point of view that he must choose the type of technology that has been tested and has rich resources.Solution. For example, for Web applications, PHP is such a reliable solution. I agree with this. asp is a technology that has failed to pass the test and has been phased out in the past few years.How is Ms? The reality is cruel

Caishuxueqian, efforts to deepen, gradually updated, there are questions please leave a message to inform, thank you.The best way to install Python third-party libraries is to use easy_install less, because Easy_install can only be installed without uninstalling, if you want to uninstall manually delete the corresponding module contents under the Lib folder that needs to go into the Python installation dire

Http://wiki.woodpecker.org.cn/moin/KarriGell Zope?! Too high, subordinates, development has a threshold! The simplicity of management does not offset the problem of development efficiency CherryPy? It's too much fun, it's too easy, and everything has to come to me ... And the last experience was incomplete Session misses unable to complete the task, upgrade? But dare not play again ... Snakelets?! With a rich and very personal development model is known, I think is pythonic Frank!
