6 Python Built-Ins That Can Replace Entire Libraries (And Make Your Code Faster)

See how Python’s built-in modules can replace third-party libraries, boost performance, cut dependencies, and make your code faster, cleaner, and easier to maintain.

We all know how easy it is to grab another library the moment a new problem shows up. If you need better date handling, you might think of installing Arrow. If you want caching, Cachetools might seem like the fix.

But the real truth is, Python already gives you a ton of built-in tools that can handle most of these jobs just fine. No need for extra installs, version headaches, or cluttering up your project.

In this article, I’ll go over six built-in Python modules that can replace some of the most popular third-party libraries. They’ll help keep your code faster, simpler, and more reliable.

Each week, I dive deep into Python and beyond, breaking it down into bite-sized pieces. While everyone else gets just a taste, my premium readers get the whole feast! Don’t miss out on the full experience – join me today!

Sticking to what’s already built into Python saves time, avoids dependency problems, and keeps your code running smoothly even when an outside package breaks or stops being supported.

By the end, you’ll see that Python’s standard library isn’t just a bunch of basic tools but rather it’s the complete toolkit that’s a lot more powerful than most people realize.

Let’s take a closer look at six built-ins that can stand in for entire libraries, help you write cleaner code, and make your programs lighter, quicker, and easier to maintain.
