How can i wrote the two following lines so for NOT to throw out
KeyErrors when a key is missing?
city = gi.time_zone_by_addr( os.environ['HTTP_CF_CONNECTING_IP'] ) or
gi.time_zone_by_addr( os.environ['REMOTE_ADDR'] ) or
"ÎγνÏÏÏη Î Ïλη"
tz = None
ip = os.environ.get('HTTP_CF_CONNECTING_IP')
if ip:
tz = gi.time_zone_by_addr(ip)

Likewise for the hostname.
Its logic is simple and straightforward but too many lines:
host = socket.gethostbyaddr( os.environ.get('HTTP_CF_CONNECTING_IP') or
os.environ.get('REMOTE_ADDR') or "Άγνωστη Προέλευση" )
this is much better in my opinion and straighforward also and more clear
to read:
No it is not and you prove that in the very next line.
it doens't work though:
If it doesn't do what you think it should do then it is not straight
forward or clear, at least not to you.
It is far better than the ifs, even easier to read, i was just missing a
[0] at the end.
host = socket.gethostbyaddr( os.environ.get('HTTP_CF_CONNECTING_IP') or
os.environ.get('REMOTE_ADDR') or "Άγνωστη Προέλευση" )[0]
