Absoultely, I had a 2 -> 3 code base I'd mostly given up on, and Claude was amazing. It even re-wrote some libraries I used without py3 versions, decided to just write the parts of the libraries I needed.

It does much better with good tests. In my case the output was a statically generated website, so I could just say 'make the same website, given these inputs'.
