Flask Sub Domain Generally used for a small number of sub-domain names, a module corresponding to a subdomain.

Flask itself can directly start the HTTP server, but due to problems such as management, deployment, and performance, we generally do not use the HTTP server of Flask itself in the production environment. From the existing practices, for Flask, a better deployment method is to use uWSGI as the WSGI container and Nginx as the front-end server. The benefits of doin

This article mainly introduces a simple tutorial on using the sqlalchemy database in the Python Flask framework, which is used to connect to and operate databases in a concise manner, for more information, see sqlalchemy in flask, which is more thorough than sqlalchemy, and simpler in some methods.

Installing flaskCall the PYTHON3 interpreter to create a flask virtual environment that is not available under Python version 3.4. The path to the PYTHON3 interpreter is first obtained by using the following command:which Python3Results:/library/frameworks/python.framework/versions/3.5/bin/python3Then create a flask project under the current path, named Microflask:mkdir MicroflaskCreate a

This learning note is mainly not to share experience, more is to record the experience of the Falsk process, after doing something in-depth research, because Django used longer, so many concepts are a look over, do a test to understand the function of the next flask.Flask is a jinja2 template, similar to Django's own template, but more powerful than the Django template, providing more useful tools that are basically consistent with basic usage.Wrote a small case, the basic steps of the template

Encyclopedia Python:python, is an object-oriented, literal translation of computer programming language; Python syntax is simple and clear, with a rich and powerful class library. It is often nicknamed the Glue language, which makes it easy to easily connect a variety of modules (especially C + +) made in other languages. A common application scenario is to use Python to quickly build a prototype of a program (sometimes even the final interface of a program), and then rewrite it in a more approp
