How to remove levels from a multi-indexed dataframe?

Question

For example, I have:

In [1]: df = pd.DataFrame([8, 9],
                          index=pd.MultiIndex.from_tuples([(1, 1, 1),
                                         


        

Answer 1

If your index has names like

       A
X Y Z
1 1 1  8
  3 2  9

Then you can also remove by specifying the index name

df.index = df.index.droplevel(Z)
