Pandas Panel: how to move along the secondary axis?

Question

What is the preferred way to iterate over all the elements (which are dataframes) in the minor axis group?

I'm currently using

pnl = pd.Panel( ... )
for key, df in pnl.transpose(2,1,0).iteritems():
   print( key )

but he looks ugly and troubled.

Answer 1

In [27]: for key in pnl.minor_axis :
   ....:         print key
   ....:         print pnl.minor_xs (key)
