deep : boolean or string, default True
Make a deep copy, including a copy of the data and the indices. With
deep=Falseneither the indices or the data are copied.
Note that when
deep=Truedata is copied, actual python objects will not be copied recursively, only the reference to the object. This is in contrast to
copy.deepcopyin the Standard Library, which recursively copies object data.
