Python’s collections module has specialized container datatypes that can be used to replace Python’s general purpose containers. The one that we’ll be focusing on here is the namedtuple which you can use to replace Python’s tuple. Of course, the namedtuple is not a drop-in replacement as you will soon see. I have seen some programmers

I noticed that CodeEval put out a post that Python is their most popular programming language for 5 years in a row! Admittedly, their Python usage has dropped 14% while others have gained, but Python has still managed to stay in the lead.

One of the first items you learn as a beginner Python programmer is how to import other modules or packages. However, I’ve noticed that even people who have used Python casually for multiple years don’t always know how flexible Python’s importing infrastructure is. In this article, we will be looking at the following topics: Regular

Today one of my coworkers came and got me so that I could explain some weird Python code they’d found. It dealt with cmake, but since it was internal code, I won’t be able to show it here. Instead, I wrote up something that has the same issues so you can see what I consider

A cache is a way to store a limited amount of data such that future requests for said data can be retrieved faster. In this article, we’ll look at a simple example that uses a dictionary for our cache. Then we’ll move on to using the Python standard library’s functools module to create a cache.

Reportlab is really nice tool for creating PDFs in Python. A little known fact is that they now support adding charts or graphs to your PDF. Previously if you wanted that functionality, you would have to do all the drawing code yourself. Unfortunately, the Reportlab guide doesn’t really explain how to use their charts, what

There is a little known tool that I wanted to talk about today. It is called wraps and it’s a part of the functools module. You can use wraps as a decorator to fix docstrings and names of decorated functions. Why does this matter? This sounds like a weird edge case at first, but if

Python comes with a fun module called functools. One of its classes is the partial class. You can use it create a new function with partial application of the arguments and keywords that you pass to it. You can use partial to “freeze” a portion of your function’s arguments and/or keywords which results in a
