With respect to using groups with findall, there are 3 cases discussed in the docs: http://docs.python.org/2/library/re#re.findall >>> a = "Bangalore, India\n\n\n" >>> re.findall(r'\w+\s*', a) # no groups ['Bangalore', 'India\n\n\n'] >>> re.findall(r'(\w+)\s*', a) # 1 group ['Bangalore', 'India'] >>> re.findall(r'(\w+)(\s*)', a) # 2+ groups [('Bangalore', ''), ('India', '\n\n\n')] CPython 2.7.3, _sre.c, pattern_findall (see 2089-2116): http://hg.python.org/cpython/file/70274d53c1dd/Modules/_sre.c#l2088 _______________________________________________ Tutor maillist - [email protected] To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
