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. If not given today is assumed. :param end_date: the end date. If not given the start date is assumed. :param tender: controls whether tender currencies should be included. :param non_tender: controls whether non-tender currencies should be included. :param include_details: if set to `True`, instead of returning currency codes the return value will be dictionaries with detail information. In that case each dictionary will have the keys ``'currency'``, ``'from'``, ``'to'``, and ``'tender'``.

If false, the pattern's precision is used. :type currency_digits: bool :param decimal_quantization: Whether decimal numbers should be forcibly quantized to produce a formatted output strictly matching the CLDR definition for the locale. :type decimal_quantization: bool :param force_frac: DEPRECATED - a forced override for `self.frac_prec` for a single formatting invocation. :return: Formatted decimal string. :rtype: str z@The force_frac parameter to NumberPattern.apply() is deprecated.r� )r r r r� rq r� r= r � ¤u ¤¤¤u ¤¤)"r r rT �str�scalebr� rr Z is_signedrQ rP r� r� rJ rK rL r) r� r� rR r� �_quantize_valuerF � _format_intr^ �_format_significantr� � partitionr@ r� r� rs r' r r( )r r� r r ra rW � force_fracrX Z is_negativer� r� r� rN �text�a�sep�bZretvalr r r r[ � s\ # �� �� �zNumberPattern.applyc C s� |� � }|d | }t|�|��t�d���}|dkrF|d| }nh|d | � }t|�} | t|| d� } dj|pxddt |d d� || | � || d � � d�d�� d�}|S )Nr� r ry z-{intpart}.{pad:0<{fill}}{fracpart}{fracextra}rq )�intpartZpad�fillZfracpartZ fracextrar= ) r� r� r� �quantizer rT r� r� r] r� rz ) r r� ZminimumZmaximumr� r� �digitsr; r� �i�jr r r r� s$ ��z!NumberPattern._format_significantc C sz t |�}||k r d|| | }| jd }d}t|�}t |�|krr||| d � | }|d | � }| jd }q6|| S )Nry r rq r� )r� r� rI ) r r� r� r� r r� Zgsize�ret�symbolr r r r� 1 s zNumberPattern._format_intc C sj t |d �}|�|�}d�|��d�\}}} |} |rP| �|| jd | jd |�} | | �| p\d||� } | S )Nr� z{:f}r= r ry )rU r� r] r� r� r� � _format_frac) r r� r r� rX ZquantumZroundedr� r� r� Z integer_partrN r r r r� > s z NumberPattern._quantize_valuec C s� |p| j \}}t|�|k r.|d|t|� 7 }|dksJ|dkrNt|�dkrNdS t|�|krt|d dkrt|d d� }qNt|�| S )Nry r rq r~ )r� r� rr r@ )r r� r r� r� r� r r r r� H s zNumberPattern._format_frac)NTTNT)N) r r r r r� r� r� r[ r� r� r� r� r r r r r� g s � | r� )N)N)N)N)NNTFF);r �rer r r7 r8 rJ Z babel.corer r r Z babel._compatr r Zlong� NameErrorrr r r r r r r r! r' r( r) r, r< r@ rB rD rF rI rO rR rU rM rd r_ rf rc rh ri rt rj rv r} Z PREFIX_ENDZ NUMBER_TOKENZPREFIX_PATTERNZNUMBER_PATTERNZSUFFIX_PATTERN�compiler� r� rZ �objectr� r r r r �<module> st � Z � 2� n� %� 0� # P �C
