to 1142331976. The hash code is then used to calculate a location in an
internal array where the value will be stored. Assuming that you're storing
keys that all have different hash values, this means that dictionaries take
constant time -- O(1), in computer science notation -- to retrieve a key. It
also means that no sorted order of the keys is maintained, and traversing the
array as the ``.keys()`` and ``.items()`` do will output the dictionary's
content in some arbitrary jumbled order that can change with every invocation of
a program.
