Python Regex, re.sub, replacing multiple parts of pattern?

Question

I can\'t seem to find a good resource on this.. I am trying to do a simple re.place

I want to replace the part where its (.*?), but can\'t figure out the syntax on how t

Answer 1

>>> import re
>>> originalstring = 'fksf var:asfkj;'
>>> pattern = '.*?var:(.*?);'
>>> pattern_obj = re.compile(pattern, re.MULTILINE)
>>> replacement_string="\\1" + 'test'
>>> pattern_obj.sub(replacement_string, originalstring)
'asfkjtest'

Edit: The Python Docs can be pretty useful reference.
