The basic graphical objects in VPython are:
.. toctree:: :maxdepth: 1 arrow box cone curve cylinder ellipsoid helix label points pyramid ring sphere 3D text <text>
You can also design your own object: See :doc:`Design New Objects <makeshapes>`
The Python function del does not work with VPython objects.
To hide a VPython object make it invisible:
ball.visible = False
