i'm using the following regex regex=re.compile("""(?P<responce_time>\s\d+\.\d+\s)""", re.M)
to get all response times in my nginx log file
line = 192.168.1.1 - - [08/Sep/2014:15:15:15 +0100]  "GET / HTTP/1.0" 200 612 "-" "-" 4.038 - .
The variable line` is always rotating with new log entries
print(Regex.match(line).groups()) 
this returns  AttributeError: NoneType Object has no attribute group
Any ideas ?
