Container object exposing keys as attributes.
Bunch objects are sometimes used as an output for functions and methods. They extend dictionaries by enabling values to be accessed by key,
bunch["value_key"], or by an attribute,
>>> from sklearn.utils import Bunch >>> b = Bunch(a=1, b=2) >>> b['b'] 2 >>> b.b 2 >>> b.a = 3 >>> b['a'] 3 >>> b.c = 6 >>> b['c'] 6
