Return a copy of the current instance.

If data is supplied then a view (reference) of data is used, and copy_data is ignored.

Parameters¶

order{‘C’, ‘F’, ‘A’, ‘K’}, optional

Controls the memory layout of the copy. ‘C’ means C-order, ‘F’ means F-order, ‘A’ means ‘F’ if a is Fortran contiguous, ‘C’ otherwise. ‘K’ means match the layout of a as closely as possible. (Note that this function and :func:numpy.copy are very similar, but have different default values for their order= arguments.) Default is ‘C’.

dataarray, optional

If supplied then use a view of data instead of the instance data. This allows copying the instance attributes and meta.

copy_databool, optional

Make a copy of the internal numpy array instead of using a reference. Default is True.

Returns¶

colColumn or MaskedColumn

Copy of the current column (same type as original)
