I tried to join these two files together using command....... from itertools import izip from os.path import exists
def parafiles(*files): vec = (open(f) for f in files if exists(f)) data = izip(*vec) [f.close() for f in vec] return data for data in parafiles('/home/amrita/alachems/chem1.txt', '/home/amrita/secstr/secstr.txt'): print ' '.join(d.strip() for d in data) it just joined the column of two files. > On Sat, Jul 18, 2009 at 12:09 AM, <amr...@iisermohali.ac.in> wrote: >> >> Hi, >> >> I have two files having entries like:-- >> fileA >> 8 Â ALA H = 7.85 N = 123.95 CA = 54.67 HA = 2.98 C = 179.39 >> 15 ALA H = 8.05 N = 119.31 CA = 52.18 HA = 4.52 C = 177.18 >> 23 ALA H = 8.78 N = 120.16 CA = 55.84 HA = 4.14 C = 179.93 >> and >> fileB >> ChainA: ALA8 Â Â -67.217297 Â Â Â -37.131330 >> ChainA: ALA21 Â -69.822977 Â Â Â -48.871282 >> ChainA: ALA23 Â -59.148095 Â Â Â -46.540043 >> ChainA: ALA33 Â -65.459303 Â Â Â -43.269718 >> >> i want to join thses two files in such a way that the output file will >> contain column of both the files and the enties of similar position of >> ALA >> will be together.so the output file should look something like:---- >> fileC >> 8 Â ALA H = 7.85 N = 123.95 CA = 54.67 HA = 2.98 C = 179.39 ChainA: >> ALA8 Â Â -67.217297 Â Â Â -37.131330 >> 15 ALA H = 8.05 N = 119.31 CA = 52.18 HA = 4.52 C = 177.18 >> Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â >> Â Â Â Â Â ChainA: >> ALA21 Â -69.822977 Â Â Â -48.871282 >> 23 ALA H = 8.78 N = 120.16 CA = 55.84 HA = 4.14 C = 179.93 ChainA: >> ALA23 Â -59.148095 Â Â Â -46.540043 >> Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â >> Â Â Â Â Â ChainA: >> ALA33 Â -65.459303 Â Â Â -43.269718 > > This mailinglist is not a collection of free code monkeys.
