Re: "import random" Odd Behavior on OSX install VPython v.3.1

For someone "very very very new" to this, you ask your question very
knowledgeably. From the first page of the VPython documentation:

As a convenience to novice programmers to provide everything that is
needed to get started, the statement "from visual import *" imports
all of the Visual features and executes "from math import *" and "from
numpy import *". It also arranges that for routines common to both
math and numpy such as sqrt, the much faster math routine is used when
possible (when the argument is a scalar rather than an array).

If you want to import the visual objects selectively, import them from
the vis module. Two simple examples:
import vis

vis.box(color=vis.color.orange,material=vis.materials.wood)

from vis import (box, color, materials)
box(color=color.orange, material=materials.wood)

There are clean modules vis.controls, vis.filedialog, and vis.graph
equivalent to the modules visual.controls, visual.filedialog, and
visual.graph. The latter versions execute "from visual import *" and
are retained because some programs expect that behavior when importing
one of these modules.

The documentation is written assuming that "from visual import *" is used.
