PropertySet
class PropertySet
Bases: dict
A default dictionary-like object
Methods
clear
PropertySet.clear() → None. Remove all items from D.
copy
PropertySet.copy() → a shallow copy of D
fromkeys
PropertySet.fromkeys(value=None, /)
Create a new dictionary with keys from iterable and values set to value.
get
PropertySet.get(key, default=None, /)
Return the value for key if key is in the dictionary, else default.
items
PropertySet.items() → a set-like object providing a view on D's items
keys
PropertySet.keys() → a set-like object providing a view on D's keys
pop
PropertySet.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
PropertySet.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
PropertySet.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
PropertySet.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
PropertySet.values() → an object providing a view on D's values
