A quick n' dirty hack for doing math and getting output in Devanagari script (Unicode) instead of ASCII.

devanagari_math.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-

def devanagari_math(statement):
    trans = {
             u'१':'1',
             u'२':'2',
             u'३':'3',
             u'४':'4',
             u'५':'5',
             u'६':'6',
             u'७':'7',
             u'८':'8',
             u'९':'9',
             u'०':'0',
             u'.':'.',
            }

    statement = statement.decode('utf-8')

    for char in trans:
        if char in statement:
            statement = statement.replace(char, trans[char])

    output = str(eval(statement))

    for char in trans:
        if trans[char] in output:
            output = output.replace(trans[char], char)

    return output

print devanagari_math('२.०/३.०')

Nice!
