set_new_attribute

set_new_attribute(obj: object, name: str, value: Any) → None

Set a new attribute for this object.

Python allows arbitrarily setting new attributes on objects at any time, but PyVista’s classes do not allow this. If an attribute is not part of PyVista’s API, an AttributeError is normally raised when attempting to set it.

Use set_new_attribute() to override this and set a new attribute anyway.

Set a new custom attribute on a mesh.

>>> import pyvista as pv
>>> mesh = pv.PolyData()
>>> pv.set_new_attribute(mesh, 'foo', 42)
>>> mesh.foo
42

This is equivalent to using allow_new_attributes with True.

>>> with pv.allow_new_attributes(True):
...     mesh.foo = 42
