This reference lists out some common errors I've seen students encounter while working in VPython. Programming languages can often generate obscure and confusing error messages, and VPython is no exception.
System/Environment Errors
If your system is not set up correctly, or the environment you are running VPython code is incorrect, a number of mysterious errors can result.
First, make sure you are running your code in VIDLE (not the identical-looking IDLE).
With the most current releases of VPython, code compiles and launches fine in IDLE, but the graphics window comes up grey and hangs.
Note that if you double-click a .py file in Windows Explorer or Finder, it may open up in the regular IDLE instead of VIDLE. To check if your code is open in VIDLE, click the "Help" menu and look for the "VPython" menu item. Regular IDLE does not have a "VPython" item in the Help menu.
