You might remember the Lisp parser we created in the article (Building Your Own Lisp Parser Part I), which is a pre-requisite for this post. You will now see how the buffered input class (UngettableInput in the previous post) can be improved. The Problems Although the UngettableInput class works for our Lisp parser, it is highly […]

While writing a full-blown compiler for a programming language is a difficult and frustrating task, writing a smaller and more specific parser can be surprisingly easy if you know a small trick. On the other hand, parsing problems pops up at several places in modern-day programming. So, learning this useful trick can be rewarding. Source: […]

In our previous redis blog we gave a brief introduction on how to interface between python and redis. In this post, we will use Redis as a cache, to build the backend of our basic twitter app. We first start the server, if it’s in a stopped state. [crayon-5b097b8f52d28383617333/] In case you have not installed […]
