Data Serialization

Which two statements correctly describe the Python dictionary data type?

Choose two
  • A The data contained in a dictionary data type cannot be removed once the dictionary has been created.
  • B The data stored in a dictionary data type is sequenced and indexed.
  • C The data contained in a dictionary data type is a key/value pair.
  • D The data stored in a dictionary data type is not sequenced or indexed.
Explanation

A Python dict is a mutable mapping of unique keys to associated values, so its contents are key/value pairs and entries may be removed. It is not a sequence and does not use positional indexes; values are retrieved by their keys. Although current Python dictionaries preserve insertion order, they remain mappings rather than sequence types.
