Ranges are encoded as single integers (start << 32 | end), not as tuples. ���� r )�sorted�range�len�append� _encode_range�tuple)r � sorted_list�ranges� last_write�i� current_range� r �?/opt/alt/python37/lib/python3.7/site-packages/idna/intranges.py�intranges_from_list s r )�start�endr c C s | d> |B S )N� r )r r r r r r " s r )�rr c C s | d? | d@ fS )Nr l �� r )r r r r � _decode_range& s r )�int_r r c C sz t | d�}t�||�}|dkrNt||d �\}}|| krF|k rNn ndS |t|�k rvt|| �\}}|| krvdS dS )z=Determine if `int_` falls into one of the ranges in `ranges`.r r TF)r �bisect� bisect_leftr r )r r �tuple_�pos�left�right�_r r r �intranges_contain* s r# ) �__doc__r �typingr r �intr r r �boolr# r r r r �<module> s
