Question1 Which Python data structure has Key-value pairs? Select one alternative: frozenset list set dictionary

Option 1: frozenset — A frozenset is an immutable version of set; it holds unordered unique elements and does not support key-value mappings, so it cannot store pairs.

Option 2: list — A list is an ordered collection of items indexed by position; it stores elements in sequence but does not associate keys with values, so it is not a key-value store.

Option 3: set — A set contains unique, unordered items and does not support mapping between keys and values; there is no concept of key-value pairs in a plain set.

Option 4: dictionary — A dictionary is a mapping data structure that stores associations between keys and values; each entry consists of a key linked to a value, which is the classic key-value pair structure.

In summary, only the dictionary provides a true key-value pairing mechanism among the options, while the others represent collections without direct key-to-value mappings.
