Stop Writing Slow Python Code! Use Threading to Supercharge Performance

Learn how Python threading can dramatically speed up your code by running tasks simultaneously. Master multi-threading to boost performance and efficiency today!

Python is great, but let’s be honest—it can be slow sometimes. If you’ve ever sat there waiting for your code to finish running, you know exactly what I mean. That’s where threading comes in.

So, what’s the deal with threading?

Well instead of making our program wait for one task to finish before moving on to the next, threading allows many things happen at the same time. Could be we’re pulling data from different websites, working with big files, or dealing with real-time data, threading helps things run faster and more efficiently.

Back when I first started writing Python scripts, I made the classic mistake of running everything one step at a time. It worked, but it was painfully slow. Once I figured out threading, it was like flipping a switch—suddenly, my programs were running smoother and faster.

Welcome to threading. Check out other 3 Random Articles here.

Imagine you're subscribed to a newsletter called 3 Randoms. Each week, it introduces you to three lesser-known Python tools that can make your coding better. It's like expanding your toolbox and discovering new tricks.

Python’s built-in threading module makes it easy to run tasks side by side, helping your program get more done in less time. Need to fetch data from multiple websites at once? Process massive text files? Run background tasks while keeping your main program responsive? Threading can handle all of that.

I won’t sugarcoat it—threading can be tricky at first. If you don’t set things up right, it can actually slow things down instead of making them faster. But once you get the hang of it, you’ll wonder how you ever coded without it.

This is just our 3 Randoms article, so I will try to use rather simple examples to help you guys get the gist of things, but this is a serious topic that deserves some longer articles of its own too.

First things first—importing the threading module:

import threading

This is great because there is no pip install, this is just built into Python. Now sit back, relax, and let your code work smarter, not harder!

Thank you for allowing me to continue to do work that I find meaningful. This is my full time job so I hope you will support my work.
