Hi, According to the doc, group(0) is the entire match.
>>> m = re.match(r"(\w+) (\w+)", "Isaac Newton, physicist") >>> m.group(0) # The entire match 'Isaac Newton' But if you do this: >>> import re >>> re.sub(r'(\d{3})(\d{3})', r'\0 to \1-\2', '757234') '\x00 to 757-234' where I expected '757234 to 757-234' Then I found that in python re '\0' is considered an octal number. So, is there anyway to refer to the entire match by an escaped notation? Thanks, Yingjie -- http://mail.python.org/mailman/listinfo/python-list
