Experienced programmers may define it on the…

A brief guide to using TOML configuration files in Python projects. — How’d you change the behavior of a software project based on a set of parameters? You could use environment variables. But what if you want complex structures in the parameters? Can you use JSON? Yes, you can. JSON files don’t allow comments. How’d you describe your parameters to readers? The…

Quickly prototype and share web apps with others. Collect feedback on predictions to improve ML model performance. — How can you share your ML model with others? Especially with those who don't have programming skills? We need an interface, don't we? A friendly UI could get the buy-in of everyone and generate a ton more feedback to improve. Previously you needed the help of a web developer to…

Transform your Jupyter notebooks into interactive dashboards — Your data science project would come along great when you have a lean technology stack. Yes, the smaller the stack, the better the project! Jupyter notebooks are inseparable from data scientists’ day-to-day work. Also, most data science projects need an interactive dashboard as well. What if you could convert your…

Here’s how you can ensure the quality of Pandas dataframes in every stage of your data pipeline — You can build a castle out of the garbage by picking the right trash. Most data science projects are like that — building castles 🏰 from the trash. In a pool of thousands of datasets in the data lake, you need to pick the right one and repair the almost-right…

The alternative I use allows for smaller file sizes and better performance. — CSVs are good, but they’re overrated. I’ve been using CSV for a very long time.

And how to avoid them getting in there? — A surprisingly simple technique to handle it. — It happens to me all the time. I create repositories, and I know that I need to store my secret keys in an environment file. But I always commit my changes without adding them to the gitignore file. As a result, our secrets are there on the internet! Now, even…

Comparing side-by-side with bubble sort and recurrence functions confirms it — Python 3.11 re-release version is out. I was curious to know what’s new in it. As I opened the changelog, the very first thing I saw captured my attention entirely. Python 3.11 is up to 10–60% faster than Python 3.10. On average, we measured a 1.25x speedup on the standard…

Let Django’s permission system take care of the authorization control — Authentication may prevent outsiders, but we need an authorization flow to control who could see what. Steramlit simplifies one of the grandest difficulties of Data Scientists — Building an app to interact with their machine learning models. It provides a set of declarative methods to create web components. But security…
