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.

Try writing correct rather than incorrect code. Or as has been repeatedly stated get somone from your CS department to help.
