not found settings.py file in this conf folder, i do not find this settings in where, this settings is not project settings, i know project settings in project root folder, but this settings in conf folder, who can tellde me this is what means? thinks

In python, an __init__.py file shares a namespace with the directory it is in. Therefore a variable settings in mezzanine/conf/__init__.py is accessible via the same name as a file mezzanine/conf/settings.py would be.

In this case mezzanine.conf.settings is defined on the final line of mezzanine/conf/__init__.py :

settings = Settings()
