discrete

Discrete(feature_name, values)

Bases: Domain, Iterable[tuple[str, float]]

A domain of discrete values.

This domain describes a discrete set of values for a feature.

Initialize the discrete domain.

Parameters:

Name	Type	Description	Default
feature_name	str	The name of the feature the domain belongs to.	required
values	list[float]	The list of values of the domain.	required

__len__()

Get the number of discrete values in the domain.

Returns:

Type	Description
int	The number of discrete values in the domain.

get_value()

Get a random value from the domain.

__iter__()

Iterate over the values of the range.
