Hi Alan,
Thank you again. I did not give a try by using
dictionary power. It works now.
Thanks again for tip.
-srini.
dida = {}
for m in nbat:
cols = m.split('\t')
old = cols[0]
dida.setdefault(old,[]).append(cols[1])
lista = ndat.split('\n')
result = []
for i in lista:
items = dida.get(i)
if items is None:
result.append(i)
else:
for x in items:
result.append(i+'\t'+x)
for x in result:
tabs = x.split('\t')
if len(tabs)>1:
for m in nmlist:
cols = m.split('\t')
colold = cols[0]
colnew = cols[1]
if tabs[1] == colold:
print x+'\t'+colnew
else:
print x

RESULT:
