Python refactoring?

[techdragon]

Currently the python component is... a bit quirky.

The a few things I've found which seem sort of easy to fix if your interested in getting PRs for each of them:

• app.py getting transformed into __main__.py and the __init__.py being echoed into the python package from a shell script, definitely resulted in several minutes of confusion looking for the python library code (which I'd like to be able to save other devs in future)
• The level of code duplication between Python app.py and JavaScript app.js seems like it could be improved but that would require one to depend on the other.
• The need to use the import module to import it as the package doesn't use a "normal import mechanism" compatible name. Some find and replace work will get this taken care of.
• Performing re.compile()(import aliased from re import compile as recompile) during class init instead of as part of a module load
• Having everything in __main__.py makes it more challenging to read and understand things than it needs to be.
• The deeply nested sections of data processing use a lot of helper functions that could be moved to the module level and tidied a bit by inverting some if conditions to remove unnecessary use of pass and putting the actually desired output inside the else

I suppose the TLDR is... There's quite a lot of refactoring opportunities in the python code (and the python packaging) but the code also looks like it has a very personal style, so if you would prefer to not have significant refactoring PRs submitted, then it would be good to know before I went ahead and wrote one, or multiple 😅
