@leigh-johnson as you are the one who most recently added a new generator, if you have the time, I would love to know if you find this useful 🙂

I am gonna try to go through it myself and add the python generator to validate nothing is missing from my side but would be great to have fresh pair of eyes 😄

:+1: Very nice work, thank you for putting together this template! Couple of quick notes that sprung to mind based on my recent experience writing the RustGenerator. I block out some time to put :eyes: on the Python generator next week if you're looking for feedback.

👍 Very nice work, thank you for putting together this template! Couple of quick notes that sprung to mind based on my recent experience writing the RustGenerator. I block out some time to put 👀 on the Python generator next week if you're looking for feedback.

Thanks for the feedback!

Would definitely appreciate some eyes on the generator if you have time! Cause my python is non-existing, I can create the generation, but knowing if it's the right output is another talk 😅 You can find the PR here: https://github.com/asyncapi/modelina/pull/863
