Its not that i don't listen, its that i want something to be implemented
in a specific way.
ipval = ( os.environ.get('HTTP_CF_CONNECTING_IP') or
os.environ.get('REMOTE_ADDR', "Cannot Resolve") )
try:
gi = pygeoip.GeoIP('/usr/local/share/GeoIPCity.dat')
city = gi.time_zone_by_addr( ipval )
host = socket.gethostbyaddr( ipval ) [0]
except socket.gaierror as e:
city = "Άγνωστη Πόλη"
host = "Άγνωστη Προέλευση"
My question was if the above code, in the except clause, can be written
in 1-line while identifying which one of the two variables have failed
to be assigned a value in the try: clause and assign to it respectively.
And i don't mean like this:
if not city:
city ="blabla"
if not host:
host="blablabla"
Can thes be witten without and if perhaps with the use of 'or' operator
in 1-line within the except clause?
