        Expand a cron expression format into a noramlized format of
        list[list[int | 'l' | '*']]. The first list representing each element
        of the epxression, and each sub-list representing the allowed values
        for that expression component.

        A tuple is returned, the first value being the expanded epxression
        list, and the second being a `nth_weekday_of_month` mapping.

        Examples:

        # Every minute
        >>> croniter.expand('* * * * *')
        ([['*'], ['*'], ['*'], ['*'], ['*']], {})

        # On the hour
        >>> croniter.expand('0 0 * * *')
        ([[0], [0], ['*'], ['*'], ['*']], {})

        # Hours 0-5 and 10 monday through friday
        >>> croniter.expand('0-5,10 * * * mon-fri')
        ([[0, 1, 2, 3, 4, 5, 10], ['*'], ['*'], ['*'], [1, 2, 3, 4, 5]], {})

        Note that some special values such as nth day of week are expanded to a
        special mapping format for later processing:

        # Every minute on the 3rd tuesday of the month
        >>> croniter.expand('* * * * 2#3')
        ([['*'], ['*'], ['*'], ['*'], [2]], {2: {3}})

        # Every hour on the last day of the month
        >>> croniter.expand('0 * l * *')
        ([[0], ['*'], ['l'], ['*'], ['*']], {})

        # On the hour every 15 seconds
        >>> croniter.expand('0 0 * * * */15')
        ([[0], [0], ['*'], ['*'], ['*'], [0, 15, 30, 45]], {})

    Generator that provides all times from start to stop matching the given cron expression.
    If the cron expression matches either 'start' and/or 'stop', those times will be returned as
    well unless 'exclude_ends=True' is passed.

    You can think of this function as sibling to the builtin range function for datetime objects.
    Like range(start,stop,step), except that here 'step' is a cron expression.
    z1The start and stop must be same type.  {0} != {1}c                 s   s(    | ]}t j |t jd dV  qd S )NrK   )rP   r   r   rN   )r@   rO  r   r   r   rB     s   & z!croniter_range.<locals>.<genexpr>Nr   rb  )r   r   r   rs   r   c                    s   |  k S r<   r   vr  r   r   cont     zcroniter_range.<locals>.contc                    s   |  kS r<   r   rn  rp  r   r   rq    rr  )rb   rP   typer=   r\   r   r   r>   r   r   r   r   r;   r   r   r   r`   )startr  r   r   r   Zexclude_endsZ	_croniterrs   r   Zauto_rtZms1Z	year_spanZicrq  rS  r\  r   rp  r   croniter_range  sZ   ,
