The conventional solution to this is:
* Read configuration settings, whether directory paths or anything else,
from a configuration file of declarative options.
* Have the program read that configuration file from one location (or a
small number of locations), and make those locations well-known in the
documentation of the program.
Python's standard library has the ‘configparser’ module, which is one
possible implementation of this.
