This is a very small utility class for using Kerberos authentication with Python requests.
To use this when making calls to a web service,
import requests
from krtc import KerberosTicket
from urllib.parse import urlparse
ws_url = "https://ws.slac.stanford.edu/ws/getData.json"
krbheaders = KerberosTicket("HTTP@" + urlparse(ws_url).hostname).getAuthHeaders()
r = requests.get(ws_url, headers=krbheaders)
print(r.json())
