Hi, I have logline that I need to test against multiple regexes. E.g.:
import re expression1 = re.compile(r'....') expression2 = re.compile(r'....') with open('log.txt') as f: for line in f: if expression1.match(line): # Do something - extract fields from line. elif expression2.match(line): # Do something else - extract fields from line. else: # Oh noes! Raise exception. However, in the "Do something" section - I need access to the match object itself, so that I can strip out certain fields from the line. Is it possible to somehow test for a match, as well as do assignment of the re match object to a variable? if expression1.match(line) = results: results.groupsdict()... Obviously the above won't work - however, is there a Pythonic way to tackle this? What I'm trying to avoid is this: if expression1.match(line): results = expression1.match(line) which I assume would call the regex match against the line twice - and when I'm dealing with a huge amount of log lines, slow things down.
