Methods

`clear`
`copy`
`fromkeys`	Create a new dictionary with keys from iterable and values set to value.
`get`	Return the value for key if key is in the dictionary, else default.
`items`
`keys`
`load`	Load an object from a JSON file.
`pop`	If key is not found, d is returned if given, otherwise KeyError is raised
`popitem`	Remove and return a (key, value) pair as a 2-tuple.
`save`	Save the object to a JSON file.
`setdefault`	Insert key with a value of default if key is not in the dictionary.
`update`	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]
`values`

Attributes

`json_path`	Return the path to the object JSON file.
`name`	Return the name of the object.
`parent_path`	Return the path to the parent directory of the object.
`path`	An alias for json_path.

clear() → None. Remove all items from D.¶

copy() → a shallow copy of D¶

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¶

property json_path¶

Return the path to the object JSON file.

Returns

pathlib.Path: The path to the object JSON file.

keys() → a set-like object providing a view on D’s keys¶

classmethod load(json_path)¶

Load an object from a JSON file.

Parameters

json_pathstr, byte or os.PathLike: The path to the JSON file containing the object data.

Raises

TypeError: If argument json_path is not a str, byte or os.PathLike.

property name¶

Return the name of the object.

Returns

str: The name of the object.

property parent_path¶

Return the path to the parent directory of the object.

Returns

pathlib.Path: The path to the parent directory of the object.

property path¶

An alias for json_path.

Returns

pathlib.Path: The path to the object JSON file.

pop(k[, d]) → v, remove specified key and return the corresponding value.¶: If key is not found, d is returned if given, otherwise KeyError is raised

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.

save(exist_ok=True)¶

Save the object to a JSON file.

Parameters

exist_okbool, optional: If set to True, any already existing object is overriden. Otherwise, if the object already exists, a FileExistsError. The default is True.

Raises

FileExistsError: If exist_ok is set to False and the object already exists.
TypeError: If any of the keys/values to be stored is not a str, int, float, bool or None.

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 dict/iterable E and F.¶: 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]

values() → an object providing a view on D’s values¶
