Python Regex Newbie- matching substrings

[Daniel]

Hi,

I would like my regex to detect that a month (any month) is in the
following line, returning the index of the start of the match:

Jun 05 14:40:26 2003 .....


So far, I've tried:

  months       = re.compile('(Jan)')
  searchResult = months.search('abcJan')
  print searchResult.start()


-Which works for just 'Jan' of course, and it correctly prints '3'. 


How do I get it to work for all months? 



I tried:

  months       = re.compile('[(Jan)(Feb)(Mar)]+')


-but that regex is too 'greedy' ie. matches too easily- I think it
matches the individual letters in each of Jan, Feb, Mar instead.


Thanks,
Daniel.
