try this:

#line whatever string you're trying replace re.sub("address = \s+", "address = 2.2.2.2", line) 

you call re.sub 3 parameters: re.sub(pattern, replacement, string_to_replace), pattern regular expression indicating want replace.

in our case pattern "address = \s+", saying match characters "address = " followed 1 or more non-whitespace chars. when re finds part of string matching pattern, replaces string put in replacement parameter, i.e. "address = 2.2.2.2".

(link docs on python's regular expressions)
