param.parameterized.Parameters.add_parameter#

Parameters.add_parameter(param_name: str, param_obj: Parameter)[source]#

Add a new Parameter object to this class.

This method allows dynamically adding a Parameter to the class, resulting in behavior equivalent to declaring the Parameter in the class’s source code.

Parameters:

param_name (str) – The name of the parameter to add.
param_obj (Parameter) – The Parameter object to add.

Examples

Create a Parameterized class:

>>> import param
>>> class P(param.Parameterized):
...     a = param.Number()
...     b = param.String()
>>> p = P()

Add a new parameter to the class P via the class namespace P.param:

>>> P.param.add_parameter('c', param.Tuple(default=(1, 2, 3)))
>>> print(p.c)
(1, 2, 3)

Add a new parameter to the class P via the instance namespace p.param:

>>> p.param.add_parameter('d', param.Tuple(default=(3, 2, 1)))
>>> p.d
(3, 2, 1)
