Group by and find top n value_counts pandas

Question

I have a dataframe of taxi data with two columns that looks like this:

Neighborhood    Borough        Time
Midtown         Manhattan      X
Melrose         B         


        

Answer 1

You can do this in a single line by slightly extending your original groupby with 'nlargest':

>>> df.groupby(['Borough', 'Neighborhood']).Neighborhood.value_counts().nlargest(5)
Borough        Neighborhood    Neighborhood  
Bronx          Melrose         Melrose           1
Manhattan      Midtown         Midtown           1
Manhatten      Lincoln Square  Lincoln Square    1
               Midtown         Midtown           1
Staten Island  Grant City      Grant City        1
