SparseDataFrame constructor raises AttributeError with SparseArray

[simonjayhawkins]

mypy error: pandas\core\sparse\frame.py:94:25: error: Item "SparseArray" of "Union[SparseSeries, SparseArray]" has no attribute "index"

Code Sample, a copy-pastable example if possible

>>> import pandas as pd
>>> pd.__version__
'0.25.0+332.g261c3a667'
>>> sa = pd.SparseArray([1,2,3])
>>> sa
[1, 2, 3]
Fill: 0
IntIndex
Indices: array([0, 1, 2])

>>> pd.DataFrame(sa)
   0
0  1
1  2
2  3
>>> pd.SparseDataFrame(sa)
__main__:1: FutureWarning: SparseDataFrame is deprecated and will be removed in a future version.
Use a regular DataFrame whose columns are SparseArrays instead.

Problem description

The docstring for SparseDataFrame states that the types accepted for the data argument of the constructor are the same types as can be passed to DataFrame.

the DataFrame constructor accepts a SparseArray, the SparseDataFrame constructor raises AttributeError: 'SparseArray' object has no attribute 'index'

Probably not worth fixing, giving that the sparse subclasses are being removed.

I agree. issue posted for visibility and cross-reference for mypy error.
