Sorry to say, but till now I have not got the solution of my problem, I
tried with this command:-
import re
if __name__ == '__main__':
data = open('chem.txt').readlines()
for line in data:
RE = re.compile('C = (.)',re.M)
matches = RE.findall(line)
for m in matches:
print line
but with this also I am getting those lines for which C value is there.
