Basically right, but in-line flags must be placed at the start of a pattern, or the result is undefined. Also in Python 2.7 re.sub() has a flags argument. Python 2.7.0+ (release27-maint:83286, Aug 16 2010, 01:25:58) [GCC 4.4.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import re >>> t = 'Python26' >>> re.sub(r'(?i)python\d\d', 'Python27', t) 'Python27' >>> re.sub(r'python\d\d', 'Python27', t, flags=re.IGNORECASE) 'Python27' Alex -- http://mail.python.org/mailman/listinfo/python-list
