This is a continuation blog. Please read Part 1 first, before reading this. Version 2: Component Based Let’s say that the data is no longer a dictionary or something that isn’t readily serialized by XML or JSON modules. For simplicity sake, let’s just create an object version of the data in part 1: Complex Data …

This will most likely be useful to you if you’re doing web applications (web services or web APIs) but the idea would still be applicable for other use cases. Since there’s really no standard way of rendering data, we usually have to support multiple format. In this blog, we’ll cover the most common formats in …

When you’ve been designing and writing systems for decades, you’d start seeing “patterns” in your own code, and if you’re lazy and smart, you’d either write a wrapper function to make multiple lines of code a single one …. or discover a built-in function that does exactly what you need. And this time it’s Python …
There’s rarely a reason to do this, but nonetheless it’s nice to know how to do it — should you have the need for it. Most of the time, we access the objects property values to do operations on them like adding or subtracting, etc. We really don’t do these operations on the object directly, …
Let’s do some multiverse madness here and do something specific but do it across different programming languages! 🙂 For this one, let’s make the class or rather the instance of it — callable; that is, instead of the client invoking its method, we invoke itself. What do I mean by this? Most of us call …
In this series, we’ll be doing some IOT-related applications using Python and Mosquitto, so if you’re interested in IOT or is currently in an environment where you hear Industry 4.0 then you wouldn’t want to miss this series 🙂 Before you proceed, make sure you’re familiar with Python, and it’s also a good idea to …
Although implementing Dependency Injection design pattern and Callbacks can be implemented in most programming languages (even in VB6), it’s just cleaner/neater to do in Python. These are also scenarios or use cases where you intentionally would pass the function object instead of it’s return value. Function as dependency To write a function that behaves differently …

One of the important (and usually confusing) concepts a developer needs to understand in Python is the use (or omission) of parentheses. This may seem so trivial, even obvious but it’s something that can cause problems to a lot of programmers, especially new ones coming from a different programming language. At best it could cause …
If you’re working on different projects, especially large projects, you should be using Python Environments. So what is a Python Environment and why should I care? The best definition is the one from the official documentation: The venv module provides support for creating lightweight “virtual environments” with their own site directories, optionally isolated from system site directories. …
In line with making apps flexible, Python really, really makes it super easy to accomplish that. And this will be (sort-of) a follow up on my previous blog about args and kwargs. If you haven’t read that, here it is: From the previous blog, we’ve seen how to pass positional and keyword arguments to a …
