I recently made the backend of a hobby Python project run entirely serverlessly on AWS, and reduced my bill from ~$300 a year to $0 a year.

There seem to be a million and 1 ways to make serverless python websites, but none of them easy. Thought I'd post in case anyone is going through the same process and this might help, or in case there are other ways I should have done this, and can be enlightened by the comment section.
