You never look in the lines you read.
if re.search('C = ',''): should be
if re.search('C = ', line):
Do you really think before you write your code? Or look at it after you
have written it?
Sorry if I offend you but you give the impression of just trying some
more or less random stuff and then asking here if it doesn't give the
required result.
That's not the attitude of a researcher, unless your definition of
research is 'asking on Usenet'.
