This is what I try to do. I solve them all (or nearly, I did one in Python only this year) in Common Lisp (my hobby language of choice), and the last few years I try to tackle them in a second language (Ada, Rust, Python, C++) up to the point that my time is too limited to do both versions (or where I find the second version is adding nothing to my understanding of the language I'm exploring).

This year I used Python as my second language (still plan to finish) but with a strong emphasis on TDD and property-based testing since I'm already familiar, but not fluent, with Python.
