i am pretty new to Odoo and i was trying to use it for a small business of my girlfirend.

I installed it and configured it and i needed to create a new module where i would gather some infos, like a report of PoS and other small things, i know it isn't necessary, but i wanted to do it for their semplicity and for practicing too.

I managed to create a new module by pycharm with the init and the manifest files. now i was wondering, since i saw the documentation and the MVC pattern, where (if possible) i could find the sources for the modules i have installed, so i could use them to collect the data i was wondering to gather. Or at least it would be useful (since i am knew to python too), to understand how it is coded and how the datas should be used.

Can you help me find (more locate in my folders since they've been installed) the sources? i would need in particular the PoS and the Purchase.

Thank you
