DynamicSpace.itemspaces#

property DynamicSpace.itemspaces#

Read-only mapping of parameter arguments to ItemSpace objects.

Returns a dictionary-like view of all ItemSpace instances created from this parameterized space. Each key is a tuple (or single value) of arguments, and each value is the corresponding ItemSpace.

This property is only meaningful for spaces with parameters defined. For spaces without parameters, this returns an empty mapping.

The keys are automatically “untuplized” for single-parameter spaces, meaning a single value is used instead of a 1-tuple.

Returns:: Read-only mapping of arguments to ItemSpace objects
Return type:: MappingProxyType

Example

>>> space.parameters = ('x', 'y')
>>> space[1, 2]  # Create ItemSpace
>>> space[3, 4]  # Create another ItemSpace
>>> space.itemspaces
{(1, 2): <ItemSpace Model1.Space1[1, 2]>,
(3, 4): <ItemSpace Model1.Space1[3, 4]>}

>>> # Single parameter - keys are not tuples
>>> space2.parameters = ('t',)
>>> space2[10]
>>> space2.itemspaces
{10: <ItemSpace Model1.Space2[10]>}
