drop first and last row from within each group

Question

This is a follow up question to get first and last values in a groupby

How do I drop first and last rows within each group?

I have this df

Answer 1

I'd apply a similar technique to what I did for the other question:

def first_last(df):
    return df.ix[1:-1]

df.groupby(level=0, group_keys=False).apply(first_last)

Answer 2

Note: in pandas version 0.20.0 and above, ix is deprecated and the use of iloc is encouraged instead.

So the df.ix[1:-1] should be replaced by df.iloc[1:-1].
