dict

Dict literals {k: v}, dict(), and methods returning dicts. Insertion order is preserved.

Method	Returns	Meaning
`.length`	number	Number of pairs, same as `len(d)`. Property: no parens (game-specific convenience)
`.keys()` / `.values()` / `.items()`	list	Keys / values / `(key, value)` tuples in insertion order (`for k, v in d.items():`)
`.has(key)`	boolean	Membership test, equivalent to `key in d` (game-specific convenience)
`.get(key, default=None)`	any	Value or default; never raises for a missing hashable key (unhashable still raises `TypeError`)
`.pop(key, default?)`	any	Remove and return; raises if missing unless a default is given
`.popitem()`	tuple	Remove and return the last inserted pair; raises when empty
`.setdefault(key, default=None)`	any	Return `d[key]` if present, else set and return `default`; useful for grouped collections
`.update(other?, **kwargs)`	None	Merge entries (dict, iterable of pairs, kwargs, or both), overwriting matching keys
`.copy()`	dict	Shallow copy (nested mutables shared)
`.clear()`	None	Remove all entries
