Claude 3.5 Sonnet for refactoring large Python files

Just tested Claude 3.5 Sonnet for refactoring a 2000-line Python file. It caught 3 bugs I missed and suggested a cleaner architecture. Took 5 minutes vs my usual 2 hours.

That’s fantastic – we’re seeing similar results with Codeium’s automated refactoring feature, shaving off nearly 80% of the time spent on those large files.

Wow, that’s incredible – I’ve been using Codeium for similar tasks and it still takes me around 3 hours, especially when dealing with nested loops like this Sonnet refactor identified!

Same experience here. Claude is surprisingly good at spotting logic errors that linters miss.

2000 lines in one go? I usually chunk it into 500-line sections. Does it handle the full context well?

That’s fantastic, but Sonnet’s initial analysis missed a critical dependency conflict within the code, requiring manual resolution – highlighting the need for human oversight even with speed gains.

That’s incredible! Could you elaborate on which specific refactoring suggestions Sonnet made regarding using type hints—did it identify any instances where type annotations were missing or incorrect?
