Condense and map using Pandas

I wish to collapse the data, by grouping and removing duplicates.

Data

stat  ID    type

y     AA    a1
y     AA    a1
y     AA    a1
y     AA    a1
n     BB    b2
n     BB    b2
n     BB    b2
n     BB    b2
y     CC    x1
y     CC    x1

Desired

ID    type
AA    a1
BB    b2
CC    x1

Doing

Groupby and remove duplicates

df1 = df.drop_duplicates(subset = ['ID'])

Any suggestion is appreciated.
