It looks like you just need to set LC_NUMERIC, as in:
Python 2.5.1 (r251:54863, Jan 17 2008, 19:35:17)
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
>>> import locale

{'mon_decimal_point': '', 'int_frac_digits': 127, 'p_sep_by_space': 127,
'frac_digits': 127, 'thousands_sep': '', 'n_sign_posn': 127,
'decimal_point': '.', 'int_curr_symbol': '', 'n_cs_precedes': 127,
'p_sign_posn': 127, 'mon_thousands_sep': '', 'negative_sign': '',
'currency_symbol': '', 'n_sep_by_space': 127, 'mon_grouping': [],
'p_cs_precedes': 127, 'positive_sign': '', 'grouping': []}
>>> print locale.format("%8.2f", 1234.56, True)
1234.56
>>> locale.setlocale(locale.LC_NUMERIC, 'en_US')
'en_US'
>>> print locale.localeconv()
{'mon_decimal_point': '', 'int_frac_digits': 127, 'p_sep_by_space': 127,

'p_cs_precedes': 127, 'positive_sign': '', 'grouping': [3, 3, 0]}
>>> print locale.format("%8.2f", 1234.56, True)
1,234.56
>>> print locale.format("%8.2f", 1234.56, False)
1234.56
