This should be either 0 or 1. :return: Returns an object for which ``getattr(dt, 'fold', 0)`` returns ``fold`` for all versions of Python. In versions prior to Python 3.6, this is a ``_DatetimeWithFold`` object, which is a subclass of :py:class:`datetime.datetime` with the ``fold`` attribute added, if ``fold`` is 1. .. versionadded:: 2.6.0 �r�����replace)�dtr���r���r���r���r ���%���s����c�������������������@���s(���e�Zd�ZdZdZdd��Zedd���ZdS�)�_DatetimeWithFoldz� This is a class designed to provide a PEP 495-compliant interface for Python versions before 3.6.

A fully initialized ``tzrangebase`` subclass should also provide the following attributes: * ``hasdst``: Boolean whether or not the zone uses DST. * ``_dst_offset`` / ``_std_offset``: :class:`datetime.timedelta` objects representing the respective UTC offsets. * ``_dst_abbr`` / ``_std_abbr``: Strings representing the timezone short abbreviations in DST and STD, respectively. * ``_hasdst``: Whether or not the zone has DST. .. versionadded:: 2.6.0 c�����������������C���s���t�d��d�S�)Nz%tzrangebase is an abstract base class)�NotImplementedErrorr(���r���r���r����__init__!��s����ztzrangebase.__init__c�����������������C���s*���|���|�}|d�u�rd�S�|r |�jS�|�jS�d�S�r ���)�_isdst�_dst_offset�_std_offset�r%���r����isdstr���r���r���r<���$��s���� ztzrangebase.utcoffsetc�����������������C���s(���|���|�}|d�u�rd�S�|r |�jS�tS�d�S�r ���)rI����_dst_base_offset�ZEROrL���r���r���r���r?���.��s���� ztzrangebase.dstc�����������������C���s���|���|�r|�jS�|�jS�d�S�r ���)rI���Z _dst_abbrZ _std_abbrr4���r���r���r����tzname8��s���� ztzrangebase.tznamec����������� ������C���s����t�|t�std��|j|�ur$td��|��|j�}|du�rF||��|��S�|\}}||�j8�}||�j8�}||f}|j dd�}|�� ||�}|r�||�j�}n ||�j�}t|�o�|�� |��} t|| d�S�)z, Given a datetime in UTC, return local time r0���r1���Nr;���r���)r2���r���r ���r���r3����transitionsr���r<���rK���r����_naive_isdstrJ���r>���r=���r ���) r%���r���rQ����dston�dstoffZutc_transitionsr@���rM���rA���rB���r���r���r���r7���?��s$���� ztzrangebase.fromutcc�����������������C���sD���|�j�s dS�|��|j�\}}|jdd�}||��ko>||�j�k�S���S�)r:���FNr;���)�hasdstrQ���r���r���rN���)r%���r����start�endr���r���r���r=���`��s ����ztzrangebase.is_ambiguousc�����������������C���sh���|�j�s dS�|d�u�rd�S�|��|j�}|d�u�r.dS�|jd�d�}|��||�}|s`|��|�r`|��|��S�|S�d�S�)NFr;���)rU���rQ���r���r���rR���r=���rB���)r%���r���rQ���rM���r���r���r���rI���v��s����ztzrangebase._isdstc�����������������C���sT���|\}}|j�d�d�}||k�r6||��ko.|k�n��}n||��koH|k�n���}|S�)Nr;���r���)r%���r���rQ���rS���rT���rM���r���r���r���rR������s����ztzrangebase._naive_isdstc�����������������C���s���|�j�|�j�S�r ���)rJ���rK���r(���r���r���r���rN������s����ztzrangebase._dst_base_offsetNc�����������������C���s ���|�|k�S�r ���r���)r%����otherr���r���r����__ne__���s����ztzrangebase.__ne__c�����������������C���s���d|�j�j�S�)Nz%s(...))r$���r)���r(���r���r���r����__repr__���s����ztzrangebase.__repr__)r)���r*���r+���r,���rH���r<���r?���r���rP���r7���r=���rI���rR���r.���rN����__hash__rY���rZ����object� __reduce__r���r���r���r���rF�����s ��� ! rF���N)r���)r���)Zsixr���� functoolsr���r���r���r���rO����__all__r����hasattrr ���r���r8���r9���rF���r���r���r���r����<module>���s��� , v
