I messed around with it a little bit. I never used gpt-4 so I can’t say how much better it is, but it worked really well and only required some minor tweaking on my part.

I've used it with Python for data extraction and visualization last week. It worked worked surprisingly well 90% of the time. But when it failed to produce the code I wanted, it was difficult to trouble shoot and find a way around.
It helped a lot to break the tasks down as much as possible. It also remembered stylistic guidelines from several prompts ago
