Used to instantiate instances of Random to get generators that don't share state. Class Random can also be subclassed if you want to use a different basic generator of your own devising: in that case, override the following methods: random(), seed(), getstate(), and setstate(). Optionally, implement a getrandbits() method so that randrange() can cover arbitrarily large ranges. � Nc �4 � | j |� d| _ y)zeInitialize an instance.

The only supported seed types are None, int, float, str, bytes, and bytearray. None or no argument seeds from current time or from an operating system specific randomness source if available. If *a* is an int, all bits are used. For version 2 (the default), all of the bits are used if *a* is a str, bytes, or bytearray. For version 1 (provided for reproducing random sequences from older versions of Python), the algorithm for str and bytes generates a narrower range of seeds. r; zlatin-1r � iCB l ���� ������r: NzOThe only supported seed types are: None, int, float, str, bytes, and bytearray.)� isinstance�str�bytes�decode�ord�map�len� bytearray�encode�int� from_bytes�_sha512�digest�type�float� TypeError�superr- r? )r@ �a�versionrA �c� __class__s �rB r- zRandom.seed� s �� �$ �a�<�J�q�3��,�7�'1�!�U�';�����#��A�"#��A�a�D� �Q���A���a�[����k�Q�&�*<�<�� !� ��Q��K�A��2�g��1�A� ��\�j��S�%��,C�D��!�S�!��H�H�J�����q�7�1�:�#4�#4�#6�6�7�A��A��T� �C���U�I�N�O�� E� F� F� ���Q����rD c �N �� | j t �| � � | j fS )z9Return internal state; can be passed to setstate() later.)�VERSIONrY r$ r? )r@ r] s �rB r$ zRandom.getstate� s �� ��|�|�U�W�-�/����@�@rD c � �� |d }|dk( r|\ }}| _ t �| � |� y|dk( r.|\ }}| _ t d� |D � � }t �| � |� yt d|�d| j ��� �# t $ r}t |�d}~ww xY w)z:Restore internal state from object returned by getstate().r r= r: c 3 �&
