Overview In the previous section we defined a simple template for the home page, and some of the modules that have not yet been implemented, such as users or posts, use mock objects as temporary placeholders. In this chapter we will see how to fill these blanks with Web forms. Web Forms are the most basic building elements in Web applications, and we will use forms to enable users to post and apply login functionality. To complete the content of this chapter, you will need the microblog app cod

Whether you are entertaining or working on linux, this is a great opportunity for you to program using python. Back to college I want them to teach me Python instead of Java, which is interesting to learn and useful in practical applications such as yum package manager. In this tutorial, I will show you how to use python and a micro-framework called flask to build a simple application to display useful information such as memory usage and CPU percenta

Getting Started with full-text search engine Unfortunately, the support of relational databases for Full-text search is not standardized. Different databases implement Full-text search in their own way, and SQLAlchemy does not provide a good abstraction in Full-text search. We now use SQLite as our database, so we can bypass SQLAlchemy and use the tools provided by SQLite to create a full-text indexing index. But it's not so good because if we switch to another database one day, we have to rew
