Read the file:

>>> import codecs
>>> pairs = [line.split() for line in codecs.open("ganesh.txt",
encoding="utf-8")]
>>> pairs[0]
[u'0', u'\u0966']

Create the conversion dictionary:

>>> trans = dict((ord(s), t) for s, t in pairs)

Do the translation: 

>>> print u"01109876".translate(trans)
०११०९८७६

You may have to use int(s) instead of ord(s) in your actual conversion code:

>>> trans = dict((int(s), t) for s, t in pairs)
>>> print u"\x00\x01\x09".translate(trans)
०१९
