xref #10360 / #10838

takes care of full slices, e.g. p.iloc[0,0,:] = [1,2,3], but the following is still failing (whether mixed blocks or not)

In [8]: axes = dict(items = pd.MultiIndex.from_tuples([('A','a'), ('B','b')]), major_axis = pd.MultiIndex.from_tuples([('A',1),('A',2)]), minor_axis=pd.MultiIndex.from_product([['X'],range(3)]))

In [9]: p = Panel(0., **axes)


In [11]: p
Out[11]: 
<class 'pandas.core.panel.Panel'>
Dimensions: 2 (items) x 2 (major_axis) x 3 (minor_axis)
Items axis: (A, a) to (B, b)
Major_axis axis: (A, 1) to (A, 2)
Minor_axis axis: (X, 0) to (X, 2)

In [13]: p.iloc[0,0,1:3]
Out[13]:

In [14]: p.iloc[0,0,1:3] = [1,2]

what would be really helpful is some more comprehensive testing to find the edge cases with panel (I added some but things take different paths so need to hit them all)

Comment From: seth-p

The example in https://github.com/pydata/pandas/issues/10360#issue-88483152 is still broken as of Pandas 0.18.0.

Comment From: jreback

it's still an open issue

Comment From: jreback

you might find xarray more convenient for representing nd data FYI

Comment From: seth-p

I looked briefly at xarray, and I like it, but I'm not ready to abandon Panels quite yet...

Comment From: jreback

closing as Panels are deprecated
