Democritus Domains
Democritus functions[1] for working with domains.
[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).
Installation
pip install d8s-domains
Usage
You import the library like:
from d8s_domains import *
Once imported, you can use any of the functions listed below.
Functions
-
def is_domain(possible_domain: str) -> bool: """Check if the given string is a domain."""
-
def domain_examples(n: int = 10) -> List[str]: """Create n domain names."""
