To expand on Paul's answer, yes they're the same. The only time order matters is detailed at [1] where the character-set "[...]" notation is detailed. Namely it needs to be unambiguous to the RE parse...to include a "-" or a "]" character in your characterset, you can either place it as the first character, or preceed it with a backslash (or otherwise make it unambiguous). Thus, if you had a more limited characterset of, say, vowels+hyphen, this regexp '[aei-ou]' is very different from '[-aeiou]' or '[aeiou-]' (the 2nd and 3rd are effectively the same) As you learn regular expressions, you'll go through a couple phases: 1) what the #$%^ is all this line-noise? 2) regexps rock! they'll solve any problem I throw at them! 3) regexps rock! I now know what types of problems the solve well without abusing them Welcome to the transition between steps #1 and #2 ;) -tim [1] http://docs.python.org/lib/re-syntax.html --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
