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?
Obviously I can't use r'\11' because there is no group 11. I know I
can use a function to do it, but it seems to me there must be a way
without. Can I escape r'\11' somehow so that it's group 1 with a '1'
after it (not group 11).
re.sub(r'(\d+)', r'\g<1>', 'string1')
