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, bunch.value_key
.
Examples
>>> 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
Create a new dictionary with keys from iterable and values set to value.
Return the value for key if key is in the dictionary, else default.
If the key is not found, return the default if given; otherwise, raise a KeyError.
Remove and return a (key, value) pair as a 2-tuple.
Pairs are returned in LIFO (last-in, first-out) order. Raises KeyError if the dict is empty.
Insert key with a value of default if key is not in the dictionary.
Return the value for key if key is in the dictionary, else default.
If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]
