ClassifierDict#
- class ClassifierDict(functions)#
Bases:
dict
[tuple
[Any
, …],list
[T
]],Generic
[T
]Dictionary that groups items by a tuple of classifier function outputs.
- Parameters:
functions (dict[str, Callable[[T], Any]]) – Mapping
label -> function(item)
used to compute the grouping key.
- __init__(functions)#
- Parameters:
functions (dict[str, Callable[[T], Any]])
- Return type:
None
Methods
__init__
(functions)append
(item)Group the given item under a key defined by its classification values.
clear
()copy
()fromkeys
(iterable[, 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.
setdefault
(key[, default])Insert key with a value of default if key is not in the dictionary.
update
([E, ]**F)If E is present and has a .keys() method, then does: for k in E.keys(): 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]
values
()- append(item)#
Group the given item under a key defined by its classification values.
- Parameters:
item (T) – The item to group.
- Return type:
None
- clear() None. Remove all items from D. #
- copy() a shallow copy of D #
- classmethod fromkeys(iterable, 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([E, ]**F) None. Update D from mapping/iterable E and F. #
If E is present and has a .keys() method, then does: for k in E.keys(): 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]
- values() an object providing a view on D's values #
