Disclaimer: I have nothing against R or Python and I'm not partial to either.

Python, the language itself, might not be a great language for data science. BUT the author can use Pandas or Polars or another data-science-related library/framework in Python to get the job done that s/he was trying to write in R. I could read both her R and Pandas code snippets and understand them equally.

This article reads just like, "Hey, I'm cooking everything by making all ingredients from scratch and see how difficult it is!".
