What is the best way to set application-wide config values?

[ajorona]

I want to write a custom logger and I want to configure the logger once, and import the logger in multiple classes. I would like to do this without using the singleton decorator. The default logger (https://docs.python.org/2/howto/logging....le-modules)[supports logging] from multiple modules, but I'm not sure how this is accomplished. If I have an application where I want to start the application, set the configuration for my own module, and import that module into other classes in the application so that I an access the configuration information, what is the best way to accomplish that?
