Storing constants

Hi,
I am storing constants either in common_site_config.json or in site_config.json.Problem here is, as I am pushing only erpnext app to production, these files are not getting updated in production. Can anyone help me in this regard.
Thanks in advance

why not add it in a python module in your app?

May i Know How to include it in a python module and access it globally in entire app?
