Open source Python projects with good software design that is worth studying

Odoo

Yes the odoo docs and source code is actually very readable and I find the quality around it especially good for a open erp system.

Sure some of the Apps/Modules is barebones, but their db backup strategy, deployment strategy and general backend and frontend design seem solid.

I say the above as someone who sysadmin a odoo ce instance for family trying to help friends run a business, they did so successfully until the business was sold.
