Democritus functions[1] for working with Python strings.
[1] Democritus functions are simple, effective, modular, well-tested, and well-documented Python functions.
We use d8s (pronounced "dee-eights") as an abbreviation for democritus (you can read more about this here).
pip install d8s-strings
You import the library like:
from d8s_strings import *
Once imported, you can use any of the functions listed below.
