[Tutor] how to read two files and substitute

[lina]

A further question:  I don't know how can I get the final output is unique?

#!/bin/python

mapping={}
for line in open("confout.pdb").readlines():
    parts=line.strip().split()
    if len(parts)>6:
        mapping[parts[1]]=parts[4]+parts[3]
origs=open("dummy.atomID").read().split()
print " ".join([mapping[orig] for orig in origs])

Thanks again,
