How to replace an re match with a transformation of that match?

Question

For example, I have a string:

The struct-of-application and struct-of-world

With re.sub

Answer 1

Try this:

>>> p = re.compile(r"((\w+-)+\w+)")
>>> p.sub('[\\1](http://\\1)','The struct-of-application and struct-of-world')
'The [struct-of-application](http://struct-of-application) and [struct-of-world](http://struct-of-world)'
