 1 | ### Python ConfigParser Example
 2 | 
 3 | This is some simple illustrative code for Python's ConfigParser module, written as I was trying to figure out how to store more complex data structures in config files.
 4 | 
 5 | In addition to the normal stuff, such as getting a single variable/value from a config file, this code also illustrates how to configure and access complex data structures from your config files, such as 
 6 | 
 7 | * dicts
 8 | * lists
 9 | * nested data structures (e.g. lists within a dict)
