TL;DR A world that scrolls infinitely in any direction, an RPG-like UI, and simple, real-time fighting. My younger kids and I built this entry for PyWeek 32 based on the theme “Neverending”. The key innovations are: It has a neverending world. As the player walks along, it picks up tiles and places new ones invisibly. It uses an LRUDict to remember the ...

Welcome to yet another How to Python article. Today, we’ll be looking at looping over dictionaries which appears to be a hot topic—at least by an organic standpoint. As it turns out, there are few ways to get it done. First, we could loop over the keys directly: for key in dictionary. Alternatively, we might only need to loop over the ...

Sometimes when we need to debug functions in Python, we need a way to write some quick timer code to capture the time-delta and to compute the time it took for the function to execute. This article shows you a quick and easy way to humanize a time-interval/time-delta without bringing in additional dependencies or libraries like Arrow or Humanize. 1 ...

Once again, I’m back with another look at some ways to solve a common Python problem. This time, we’ll be looking at how to split a string by whitespace (and other separators) in Python. If you’re in a rush, here’s the key takeaway. You could write your own whitespace splitting function, but they’re often slow and lack robustness. Instead, you ...

As this series grows, I’ve started poking at seemingly simple problems to expose their complexity. This time, I thought it would be interesting to look at how to convert a string to lowercase. As it turns out, there’s a really straightforward solution (lower()), but I think it’s worth looking at a few homemade solutions first. For instance, we could try ...

Remember learning to round in grade school? Me too! The only problem is I don’t use the idea very often. As a result, I don’t always remember how to round a number in programming contexts like Python. Luckily, I’ve pieced together a little article for myself. Hopefully, you get some value out of it as well. As it turns out, ...

If you’re working with Python for the first time, you might be interested in learning how to store data. For example, you might want to collect a list of exam scores, so you can average them. If so, the list data structure gets the job done. But, how do you create a list in Python? That’s the topic of today’s ...

As Python is increasingly used for computation, it becomes more important for math related resources to be made available. To aid in that effort, I figured I’d share a few ways to compute absolute value in Python. As it turns out, there are a few ways to compute absolute value in Python. First, there’s the abs() function which comes built ...
