The word you want, rather than "environment", is "locale".  The issue of
decimal point separator is one of the "locale conventions", queried via
locale.localeconv().

    >>> import locale
    >>> locale.getlocale()
    (None, None)
    >>> locale.getdefaultlocale()
    ['en_AU', 'utf']

    >>> locale.localeconv()['decimal_point']
    '.'
    >>> locale.localeconv()['mon_decimal_point']
    ''

    >>> locale.localeconv()
    {'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': []}

Read about what each of these convention values mean:
