It is pretty common to have a configuration module that is imported 
wherever the configuration is needed. This is simple but it is 
essentially global state and shares some of the disadvantages of 
globals; in particular it couples all your code to the settings module 
and makes testing more difficult.

The alternative is to pass a configuration object to whatever needs it. 
This eliminates the coupling but is more painful to implement.
