Test script for :func:`bidict.namedbidict`::
|
||
|
|
|
||
|
|
>>> from bidict import namedbidict
|
||
|
|
>>> ElementMap = namedbidict('ElementMap', 'symbol', 'element')
|
||
|
|
>>> noble_gases = ElementMap(He='helium')
|
||
|
|
>>> noble_gases.element_for['He']
|
||
|
|
'helium'
|
||
|
|
>>> noble_gases.symbol_for['helium']
|
||
|
|
'He'
|
||
|
|
>>> noble_gases.element_for['Ne'] = 'neon'
|
||
|
|
>>> del noble_gases.symbol_for['helium']
|
||
|
|
>>> noble_gases
|
||
|
|
ElementMap({'Ne': 'neon'})
|
||
|
|
|
||
|
|
Comparison works as expected::
|
||
|
|
|
||
|
|
>>> from bidict import bidict
|
||
|
|
>>> noble_gases2 = ElementMap({'Ne': 'neon'})
|
||
|
|
>>> noble_gases2 == noble_gases
|
||
|
|
True
|
||
|
|
>>> noble_gases2 == bidict(noble_gases)
|
||
|
|
True
|
||
|
|
>>> noble_gases2 == dict(noble_gases)
|
||
|
|
True
|
||
|
|
>>> noble_gases2['Rn'] = 'radon'
|
||
|
|
>>> noble_gases2 == noble_gases
|
||
|
|
False
|
||
|
|
>>> noble_gases2 != noble_gases
|
||
|
|
True
|
||
|
|
>>> noble_gases2 != bidict(noble_gases)
|
||
|
|
True
|
||
|
|
>>> noble_gases2 != dict(noble_gases)
|
||
|
|
True
|
||
|
|
|
||
|
|
Test ``base_type`` keyword arg::
|
||
|
|
|
||
|
|
>>> from bidict import frozenbidict
|
||
|
|
>>> ElMap = namedbidict('ElMap', 'sym', 'el', base_type=frozenbidict)
|
||
|
|
>>> noble = ElMap(He='helium')
|
||
|
|
>>> hash(noble) is not 'an exception'
|
||
|
|
True
|
||
|
|
>>> noble['C'] = 'carbon' # doctest: +ELLIPSIS
|
||
|
