is possible reggular expressions, , best way reggular expressions?

you can read regular expressions in python in standard library documentation. here, i'm using named groups store matched value dictionary structure key choose.

>>> import re >>> s = '#ff0000 hexcode color red' >>> m = re.match(r'(?p<hexcode>.+) hexcode color (?p<color>.+)', s) >>> m.groupdict() {'color': 'red', 'hexcode': '#ff0000'} 

note if there's no match using regular expression, m object here none.
