In addition to that the currency database distinguishes between tender and non-tender currencies. By default only tender currencies are returned. The return value is a list of all currencies roughly ordered by the time of when the currency became active. The longer the currency is being in use the more to the left of the list it will be. The start date defaults to today. If no end date is given it will be the same as the start date. Otherwise a range can be defined. For instance this can be used to find the currencies in use in Austria between 1995 and 2011: >>> from datetime import date >>> get_territory_currencies('AT', date(1995, 1, 1), date(2011, 1, 1)) ['ATS', 'EUR'] Likewise it's also possible to find all the currencies in use on a single date: >>> get_territory_currencies('AT', date(1995, 1, 1)) ['ATS'] >>> get_territory_currencies('AT', date(2011, 1, 1)) ['EUR'] By default the return value only includes tender currencies. This however can be changed: >>> get_territory_currencies('US') ['USD'] >>> get_territory_currencies('US', tender=False, non_tender=True, ... start_date=date(2014, 1, 1)) ['USN', 'USS'] .. versionadded:: 2.0 :param territory: the name of the territory to find the currency for. :param start_date: the start date.

In that case each dictionary will have the keys ``'currency'``, ``'from'``, ``'to'``, and ``'tender'``. territory_currenciesNrcs |dus|ko|dup|kSNr)startendend_date start_daterr _is_activesz,get_territory_currencies.._is_active)rfromtotender) rdate_todayr datetime_rr&r!append) territoryr;r:r? non_tenderinclude_detailsrcursr<result currency_coder7r8 is_tenderrr9rget_territory_currenciessD4    rKcCt|jddS)zReturn the symbol used by the locale to separate decimal fractions. >>> get_decimal_symbol('en_US') u'.' :param locale: the `Locale` object or locale identifier r.rrnumber_symbolsr&rrrrget_decimal_symbolrQcCrL)zReturn the plus sign symbol used by the current locale. >>> get_plus_sign_symbol('en_US') u'+' :param locale: the `Locale` object or locale identifier plusSign+rNrPrrrget_plus_sign_symbol#rRrUcCrL)zReturn the plus sign symbol used by the current locale. >>> get_minus_sign_symbol('en_US') u'-' :param locale: the `Locale` object or locale identifier minusSign-rNrPrrrget_minus_sign_symbol.rRrXcCrL)zReturn the symbol used by the locale to separate mantissa and exponent. >>> get_exponential_symbol('en_US') u'E' :param locale: the `Locale` object or locale identifier exponentialErNrPrrrget_exponential_symbol9rRr[cCrL)zReturn the symbol used by the locale to separate groups of thousands. >>> get_group_symbol('en_US') u',' :param locale: the `Locale` object or locale identifier group,rNrPrrrget_group_symbolDrRr^cCstdtt||dS)afReturn the given number formatted for a specific locale. >>> format_number(1099, locale='en_US') u'1,099' >>> format_number(1099, locale='de_DE') u'1.099' .. deprecated:: 2.6.0 Use babel.numbers.format_decimal() instead. :param number: the number to format :param locale: the `Locale` object or locale identifier z+Use babel.numbers.format_decimal() instead.rP)warningswarnDeprecationWarningformat_decimal)numberrrrr format_numberOs  rdcCs4t|tjsJ|}|jdkrdSt|jS)zReturn maximum precision of a decimal instance's fractional part.
