For example, I have:
In [1]: df = pd.DataFrame([8, 9],
index=pd.MultiIndex.from_tuples([(1, 1, 1),
(1, 3, 2)]),
columns=['A'])
In [2] df
Out[2]:
A
1 1 1 8
3 2 9
Is there a better way to remove the last level from the index than this:
In [3]: pd.DataFrame(df.values,
index=df.index.droplevel(2),
columns=df.columns)
Out[3]:
A
1 1 8
3 9
