Bunch
(class from pyomo.common.collections.bunch
)
- class pyomo.common.collections.bunch.Bunch(*args, **kw)[source]
Bases:
dict
A class that can be used to store a bunch of data dynamically.
This class allows for unspecified attributes to have a default value of None. This borrows the output formatting ideas from the ActiveState Code Container (recipe 496697).
For historical reasons, attributes / keys are stored in the underlying dict unless they begin with an underscore, in which case they are stored as object attributes.
Methods
__init__
(*args, **kw)clear
()copy
()fromkeys
([value])Create a new dictionary with keys from iterable and values set to value.
get
(key[, default])Return the value for key if key is in the dictionary, else default.
items
()keys
()pop
(k[,d])If the key is not found, return the default if given; otherwise, raise a KeyError.
popitem
()Remove and return a (key, value) pair as a 2-tuple.
set_name
(name)setdefault
(key[, default])Insert key with a value of default if key is not in the dictionary.
update
(d)The update is specialized for JSON-like data.
values
()Member Documentation
- clear() None. Remove all items from D.
- copy() a shallow copy of D
- fromkeys(value=None, /)
Create a new dictionary with keys from iterable and values set to value.
- get(key, default=None, /)
Return the value for key if key is in the dictionary, else default.
- items() a set-like object providing a view on D's items
- keys() a set-like object providing a view on D's keys
- pop(k[, d]) v, remove specified key and return the corresponding value.
If the key is not found, return the default if given; otherwise, raise a KeyError.
- popitem()
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.
- setdefault(key, default=None, /)
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.
- update(d)[source]
The update is specialized for JSON-like data. This recursively replaces dictionaries with Bunch objects.
- values() an object providing a view on D's values
