Convert numeric strings to superscript

I need convert numeric strings to superscript, is there a better (built-in) way of doing it?

def to_sup(s):
    sups={u'1': u'\xb9', 
          u'0': u'\u2070',
          u'3': u'\xb3', 
          u'2': u'\xb2',
          u'5': u'\u2075',
          u'4': u'\u2074',
          u'7': u'\u2077',
          u'6': u'\u2076',
          u'9': u'\u2079',
          u'8': u'\u2078'}
    if s.isdigit():
        return ''.join([sups[i] for i in s])
print to_sup('0123')

Output:

⁰¹²³

Your way is slightly incorrect. Better would be:

def to_sup(s):
    sups = {u'0': u'\u2070',
            u'1': u'\xb9',
            u'2': u'\xb2',
            u'3': u'\xb3',
            u'4': u'\u2074',
            u'5': u'\u2075',
            u'6': u'\u2076',
            u'7': u'\u2077',
            u'8': u'\u2078',
            u'9': u'\u2079'}

    return ''.join(sups.get(char, char) for char in s)  # lose the list comprehension

s.isdigit() will only check the first letter, which probably doesn't make sense.

If for some reason you want a one-liner:

u''.join(dict(zip(u"0123456789", u"⁰¹²³⁴⁵⁶⁷⁸⁹")).get(c, c) for c in s)
