Ask HN: Best Resources for Daily Bite-Sized Python, Patterns, and Concepts?

Hi HN-Community, I'm looking for a resource to learn small but advanced Python concepts, programming patterns, or general CS concepts daily. I want to incorporate a 15-30 minute routine to improve my skills in Python, algorithms, and software design.

Most resources I find are too basic. Can you recommend any books or websites that offer structured, bite-sized learning for intermediate to advanced developers?
