re.sub: escaping capture group followed by numeric(s)

Hi All, (I reckon this is probably a question for MRAB and is not really Python specific, but anyhow...) Absolutely basic example: re.sub(r'(\d+)', r'\1', 'string1') I've been searching around and I'm sure it'll be obvious when it's pointed out, but how do I use the above to replace 1 with 11? O
