flask or django for web development

This article mainly introduces the simple performance test results of common python web frameworks (including django, flask, bottle, tornado ), for more information about the performance of django, flask, bottle, and tornado frameworks. The performance of

When developing Web apps using Django or Flask, it is common to develop and debug programs with built-in servers, which are then transferred to the production environment for deployment. The problem is that these built-in servers usually do not support HTTPS, we want to be able to use and test https at development time

Using the Django or Flask framework to develop web apps typically uses built-in server development and debugging programs, which are then transferred to the production environment when the program is completed. The problem is that these built-in servers typically do not support HTTPS, and we want to be able to use and

FlaskThe Python Mini Web framework is based on the JINJA2 template engine and the Werkzeug Wsgi Toolbox. Flask is easy to use and uses extension to add additional functionality. Flask There is no form validation tool, SQL is used by default. However, flask preserves amplification and can use

introduce them in the template: {% import ' macros.html ' as macros%} Some of the code in the template repeats itself in different places, save the part as a file, include come in as needed, and avoid repeating the writing: {% include ' common.html '%} Another important way to increase reusability is template inheritance, similar to the inheritance of classes in Python code. Define a basic template first: ' base.html ': The block elements in the tag can be changed in the inherited template. A c
