you need to specify the axis of concatenation (it defaults to 0, the items axis) In [12]: pd.concat([pan1, pan2],axis=1) Out[12]: <class 'pandas.core.panel.Panel'> Dimensions: 2 (items) x 12 (major_axis) x 2 (minor_axis) Items axis: X to Y Major_axis axis: 0 to 11 ...
Now suppose we attempt to use theconcat()function to append the two DataFrames into one DataFrame: #attempt to append two DataFrames togethercombined = pd.concat(df1, df2, ignore_index=True)#view final DataFrameprint(combined) TypeError: first argument must be a...
