Django is a very nice framework. Over the year however, I have seen Django Framework to be abused in all sorts of different ways. In this post series we will have a look at rules to live by, to run a successful Django project. In this post I want to focus on - Know your framework.

I like Clojure a lot. While I don’t make a living with it, to me, it’s by far the most fun language to code in. Sometimes I miss some of its features in Python. In this short post I will show you how to make Python dictionaries working like Clojure maps.

Quite often you want to perform some kind of action, based on the type of the argument provided to the function. There are multiple ways of doing that. Most of the time I would create a dictionary with a mapping, but there are cleaner solutions to that problem. Python Standard Library provides many tools for writing cleaner, and safer code.

If I were to pick one Python trick that helps to save you thousands of dollars in unnecessary code refactoring, it would be dependency inversion. In this short example, I am going to show a simple trick that will potentially save you from a lot of frustration and help you write more future-proof code.
