For experienced programmers
As a convenience to novice programmers to provide everything that is needed to get started, GlowScript VPython by default imports all of the VPython features and includes standard math functions such as sqrt. The documentation is written as though "from vpython import *" were present.
You can however import selectively, as shown in the following examples, which are compatible with Jupyter VPython. (To help with converting from Classic VPython, you can refer to "vis" or "visual" instead of "vpython".)
import vpython
import vpython as vp # "vp" is any name of your choice
from vypthon import box, color
