How Python Boolean Operators Work

To start, I’ll give an update on my video series. I’ve recorded my first episode, but I’ve had a ton of troubles when trying to edit it. The application keeps crashing, which is okay, since it recovers most of what I did, but it does grow tedious. I’ve also decided to start the editing over due to a few factors. Lastly, I’ve started recording a series of videos with my best friend for his gaming YouTube channel. All of that together has led me to put off the my video series for a while and get back to writing on the blog. I’ll get back to the video series when I’ve finished recording with my friend. It could take a while.

Python Boolean Operator Confusion

A while back, I stumbled upon a post asking about the how the following lines could possibly right:
'a' == 'b' or 'a' returns 'a'
'a' == 'a' and 'b' returns 'b'

He had a few other lines that did what you might expect, returning True and False. But why do these and and or operators not always return boolean values? To answer that, I’d like to dig into Python’s history. Continue Reading

“Object Literals” in Python

This may come as a shock to my regular readers, but even as a Pythonista and Kotlinite, I’m a little jealous of JavaScript. That’s right; I – a JS hater – am jealous of JavaScript. More specifically, I’m jealous of JavaScript’s object literals (also full-featured function literals, but I don’t think I can do anything about that). Yes, in many respects, JS object literals are almost exactly the same thing as Python’s dicts, but there is one important difference: dot notation access.

So here’s my attempt at accomplishing the closest thing possible toward making object literals in Python. Continue Reading

The Yin and Yang of Python

It’s time that I got a bit more real with you guys. Pretty much ever since I learned Python, I’ve been touting it as a super amazing language. I’ve been doing the same with Kotlin, but this is about Python.

Now, this doesn’t mean I’m going to be changing my tupython yin yangne from here on out; after this, I’m not really going to bringing up the weak points of Python. I’m just going to continue talking about strong principles, practices, features, and tips and tricks. But this article was just inspired by a small revelation, and I decided to just roll with it.

That inspiration was due to the revelation that the official Python logo looks vaguely like a yin yang symbol (apparently, it’s called the Taijitu). To prove it, I made an alteration to the symbol, changing just the colors.

So, let’s look at the pros and cons of Python. Continue Reading

Intro

In today’s article, we follow up last week’s article about making Kotlin-like builders in Java and Python, expanding the builder APIs to take some of the optional parameters for more flexibility. We continue on with our HTML example, trying to add tag attributes, such as class, id, and style. Continue Reading
