.. py:function:: ak.from_regular(array, axis=1, highlevel=True, behavior=None)


    :param array: Array to convert.
    :param axis: The dimension at which this operation is applied. The
             outermost dimension is ``0``, followed by ``1``, etc., and negative
             values count backward from the innermost: ``-1`` is the innermost
             dimension, ``-2`` is the next level up, etc.
    :type axis: int
    :param highlevel: If True, return an :py:obj:`ak.Array`; otherwise, return
                  a low-level :py:obj:`ak.layout.Content` subclass.
    :type highlevel: bool
    :param behavior: Custom :py:obj:`ak.behavior` for the output array, if
                 high-level.
    :type behavior: None or dict

Converts a regular axis into an irregular one.

.. code-block:: python


    >>> regular = ak.Array(np.arange(2*3*5).reshape(2, 3, 5))
    >>> ak.type(regular)
    2 * 3 * 5 * int64
    >>> ak.type(ak.from_regular(regular))
    2 * var * 5 * int64
    >>> ak.type(ak.from_regular(regular, axis=2))
    2 * 3 * var * int64
    >>> ak.type(ak.from_regular(regular, axis=-1))
    2 * 3 * var * int64
