cf.Count.copy

Count.copy(data=True)

Return a deep copy.

f.copy() is equivalent to copy.deepcopy(f).

Arrays within Data instances are copied with a copy-on-write technique. This means that a copy takes up very little extra memory, even when the original contains very large data arrays, and the copy operation is fast.

New in version 1.7.0.

If False then do not copy data. By default data are copied.

Returns:

The deep copy.

Examples:

>>> g = f.copy()
>>> g = f.copy(data=False)
>>> g.has_data()
False
