Starting with pytest’s parametrize
If you’re writing test cases, I strongly suggest using pytest’s parametrize feature. It helps you save both time and code. In this article, Ned Batchelder explained how to use it with a clear example.

Expressions are coming to pandas!
Pandas was introduced 17 years ago and quickly became the go-to tool for data science in Python. Over time, new libraries appeared, building on pandas’ ideas while fixing some of its limitations. Now, pandas has come full circle with a new syntax inspired by those newer libraries. In this article, Marco Gorelli explains why this change happened and how you can use it.
