But i'm Steven! That why i make use of it to read it immediately after 
my script run at browser time.

i have even included a sys.exit(0) after the try:/except block:

Here is it:


errout = open( '/tmp/err.out', 'w' )		# opens and truncates the error 
output file
try:
	gi = pygeoip.GeoIP('/usr/local/share/GeoIPCity.dat')
	city = gi.time_zone_by_addr( os.environ['REMOTE_ADDR'] ) or 
gi.time_zone_by_addr( os.environ['HTTP_CF_CONNECTING_IP'] )
	host = socket.gethostbyaddr( os.environ['REMOTE_ADDR'] )[0] or 
socket.gethostbyaddr( os.environ['HTTP_CF_CONNECTING_IP'] )[0] or "Proxy 
Detected"
except Exception as e:
	print( "Xyzzy exception-", repr( sys.exc_info() ), file=errout )
     errout.flush()

sys.exit(0)

and the output of error file is:


nikos at superhost.gr [~]# cat /tmp/err.out
UnicodeDecodeError('utf-8', b'\xb6\xe3\xed\xf9\xf3\xf4\xef 
\xfc\xed\xef\xec\xe1 \xf3\xf5\xf3\xf4\xde\xec\xe1\xf4\xef\xf2', 0, 1, 
'invalid start byte')
