unique_by_id
unique_by_id(iterable, /)
Return unique objects in iterable
, by identity.
>>> a = {0}
>>> list(unique_by_id([a, a]))
[{0}]
:rtype: :sphinx_autodoc_typehints_type:`\:py\:class\:\`\~collections.abc.ValuesView\``
>>> list(unique_by_id([a, a.copy()]))
[{0}, {0}]
Parameters
iterable (Iterable)
Return type
unique_by_eq
unique_by_eq(iterable, /)
Return unique objects in iterable
, by equality.
This function is only appropriate if (i) there are a small number of objects, and (ii) the objects are not guaranteed to be hashable. Otherwise, a dict
or set
is a better choice.
This function may potentially make a comparison between all pairs of elements, so it executes in time in the worst case, in contrast to a dict
or set
, both of which can be constructed in time.
>>> a = {0}
>>> list(unique_by_eq([a, a]))
[{0}]
:rtype: :sphinx_autodoc_typehints_type:`\:py\:class\:\`list\``
>>> list(unique_by_eq([a, a.copy()]))
[{0}]
Parameters
iterable (Iterable)
Return type
