The generated example code is edited just to demostrate potential improvements to the python codegen. The main changes are using sqlalchemy as the exection engine and using stdlib dataclasses instead of pydantic. This also eliminates the runtime package.
Generated python code now only depends on sqlalchemy. Query functions are now inside classes as well.

Github actions was having issues yesterday, which caused the tests to fail. I've pushed the rebased commits which triggered a new test run. |

Based on comments on my initial python codegen PR I've put together some potential changes to the generated python code.
I've marked this as a draft PR because I've only made manual edits to the authors example. Once we have a more solid idea of what the generated python code should look like I'll make the changes to the actual codegen code.
A quick overview of the changes:
$1is replaced with:p1instead of just%s.Notes:
:character is special to sqlalchemy. The codegen will need to replace:with\\:in queries. I don't think this will cause issues, but there's always the potential for edge-case issues with regex replaces on the queries.
