From 2b2b3f9bcb7d1cdf97b68f825489b5abfd42cf22 Mon Sep 17 00:00:00 2001 From: Guido van Rossum Date: Mon, 12 Jan 1998 18:57:53 +0000 Subject: Fix two bugs: (1) maxsplit was ignored in split(). (2) groups() would return a string instead of a singleton tuple when there was only one group. --- Lib/re.py | 13 ++++++++----- 1 file changed, 8 insertions(+), 5 deletions(-) diff --git a/Lib/re.py b/Lib/re.py index b3c266c..3fb9408 100644 --- a/Lib/re.py +++ b/Lib/re.py @@ -203,6 +203,7 @@ class RegexObject: if type(g)==type( "" ): g = [g] results[len(results):] = list(g) pos = lastmatch = j + n = n + 1 results.append(source[lastmatch:]) return results @@ -259,11 +260,13 @@ class MatchObject: def groups(self): "Return a tuple containing all subgroups of the match object" - - # If _num_regs==1, we don't want to call self.group with an - # empty tuple. - if self.re._num_regs == 1: return () - return apply(self.group, tuple(range(1, self.re._num_regs) ) ) + result = [] + for g in range(1, self.re._num_regs): + if (self.regs[g][0] == -1) or (self.regs[g][1] == -1): + result.append(None) + else: + result.append(self.string[self.regs[g][0]:self.regs[g][1]]) + return tuple(result) def group(self, *groups): "Return one or more groups of the match." -- cgit v0.12
