Hi,

I have a file having lines:-

48 ALA H = 8.33 N = 120.77 CA = 55.18 HA = 4.12 C = 181.50
104 ALA H = 7.70 N = 121.21 CA = 54.32 HA = 4.21 C =
85 ALA H = 8.60 N =  CA =  HA = 4.65 C =

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
f = open('chem.txt')
for line in f:
     if re.search('C = ',''):
        print line

but i am not getting the desired output.


Gosh. Must be groundhog-day. Again.

And there is me thinking that my job could be endangered by cheap & qualified indian soft-workers - can't be to many of them around if the OP doesn't get a hold of one for the better part of a month now. Must be one of those management myths they tell you to scare you into a less well paid contract...
