The locale module provides this functionality.

>>> import locale
>>> locale.setlocale(locale.LC_ALL, '')
'English_United States.1252'
>>> print locale.currency(1205466.654)
$1205466.65
>>> locale.currency(1205466.654, grouping=true)
$1,205,466.65

That's using the default locale.  For me, that's US English.  Other
languages and countries have different ways of showing currency:

>>> locale.setlocale(locale.LC_ALL, "fr")
'French_France.1252'
>>> print locale.currency(1205466.654, grouping=True)
1 205 466,65 €
