How to Monitor Domain Expiration Dates in Python
A Python script that checks domain expiration dates using the python-whois library and warns when a domain is expiring soon.
import whois
from datetime import datetime, timedelta
import time
def check_domain_expiry(domain_name):
"""Check when a domain expires and warn if soon."""
try:
w = whois.whois(domain_name)
expiry = w.expiration_date
# Handle list or single date
if isinstance(expiry, list):
…Parse WHOIS Data with Python Regex
Extract domain registration fields from a mock WHOIS record using regex and compute days until expiration.
import re
from datetime import datetime
def parse_whois(whois_text: str) -> dict:
"""Extract key registration fields from a mock WHOIS record."""
patterns = {
"domain": r"Domain Name:\s*(.+)",
"registrar": r"Registrar:\s*(.+)",
"creation_date": r"Creation Date:\s*(.+)",
