Dear all,
Can anyone tell me that suppose i have a file having content like:
_Atom_name
_Atom_type
_Chem_shift_value
_Chem_shift_value_error
_Chem_shift_ambiguity_code
1 1 PHE H H 8.49 0.02 1
2 1 PHE HA H 4.60 0.02 1
3 1 PHE CA C 57.83 0.3 1
4 2 LEU H H 8.23 0.02 1
5 2 LEU HA H 4.25 0.02 1
6 2 LEU HB2 H 1.54 0.02 1
7 3 ASP H H 8.10 0.02 1
8 3 ASP HA H 4.52 0.02 1
9 3 ASP HB2 H 2.65 0.02 1
stop
now what i want that instead of copying all the lines it will just write
the information about PHE and ASP then how i acn do that using python
programming.Kindly tell me the command for that.
try something like:
for line in open("filename").readlines():
if (re.search("PHE|ASP",line):
print line
The readlines() is unnecessary, and if your file is at all long you'd
be better off precompiling the regular expression.
import re
expr = re.compile("PHE|ASP")
with open("filename") as f:
for line in f:
if expr.search(line):
print line
