If you're doing this for thousands separators, look at the locale module:
>>> import locale
>>> locale.setlocale(locale.LC_ALL, 'US') #the default C locale
doesn't do grouping
'English_United States.1252'
>>> locale.format_string('%d', 10000, grouping=True)
'10,000'
>>> locale.format_string('%d', 12332321, grouping=True)
'12,332,321'
>>>

I only have the US locale available on this machine, but if you use a
locale that uses "." as the thousands separator, this should work for
you.
