Answer 1

You need to capture the text which exists next to =

p = re.match(r'.for[^=]*=\s*(.*)',dict['comment'])
if p:
    print '%s' %p.group(1)

Answer 2

You could also use the native string.split() if the entire string is .for $i = 5 .. 13 :

s = dict['comment']
if '.for' in s:
    output = s.split('=')[1]
#output is then: " 5 .. 13"
