There are several common ways to do this.
- have a configuration module that parses the settings and contains the 
results. Modules that need access to the configuration import the config 
module and read its values
- create a configuration object that is passed as a parameter to 
functions that need it, or pass individual configuration items to the 
functions.
- create a configuration object that is stored as an attribute of a 
class and accessed that way
