A simple blog system and a Flask Learning Guide for the flask framework I wrote an article about building a flask development environment. Today, I will continue with a practical small project-blog system. The blog system is very simple. There is only one page, and the sparrow is small and dirty. The purpose here is not to create a project for the purpose of doin

Because the 0.1 version of the overall code is about 350 lines, relatively simple. Therefore, this article will be based on the flask 0.1 version of the source code to analyze the Flask application startup process.Flask Reference Flask, the website has one of the simplest apps:From flask Import Flaskapp =

Storing data in a database is an integral part of any software application. Regardless of the control of the database there is a master control of that data. Blockchain technology stores data in chunks within a blockchain network. As a result, as long as a node is synchronized with the network, they get a copy of the data in the chunk. Therefore, there is no specific data master in this technology.In this tutorial, we'll write a smart contract (which I'll explain further) to keep the user data o
