Now i want to make two another file in which i want to put those lines
for
which C is missing and another one for which N,CA and C all are missing,
I tried in this way:
import re
expr = re.compile("C = None")
This will search for the literal string 'C = None' which does not exist in
your sdata.
You need to search for 'C = 'at the end of the line (assuming it is always
there.
Otherwise you need to search for 'C = ' followed by a non number.)
