Let us create a new dataframe myframe2 that is the same as myframe except for an extra entry [‘red’,’pencil’,0.8] at index 5.

1. myframe2 = myframe

2. myframe2.loc[5]=[‘red’,’pencil’,0.8]

3. myframe2

Output:

Now, we group myframe2 by color as well as by object.

1. mygroup2 = myframe2[‘price’]. groupby([myframe2[‘color’],myframe2[‘object’]])

2. mygroup2.groups

Output:

{(‘blue’, ‘ball’): Int64Index([0], dtype=’int64’),

(‘red’, ‘paper’): Int64Index([3], dtype=’int64’),

(‘red’, ‘pencil’): Int64Index([2, 5], dtype=’int64’),

(‘white’, ‘mug’): Int64Index([4], dtype=’int64’),

(‘white’, ‘pen’): Int64Index([1], dtype=’int64’)}
