Re: [sage-support] Animating 3D object with frame_list
1) Remove var('t'): this is to declare a *symbolic (mathematical)*
variable and is completely useless here
2) replace "frame_list = frame_list + Pall" with "frame_list.append(Pall)"

[sage-support] Re: notebook () - Shell
You get back to the web interface with Right-Ctrl Fn, where n is some number between 1 and 7. Probably F7. I don't understand what you mean by "but no code will be in web interface", you just get back to where you were.

Hopefully someone who uses the VM solution can try this out and get you back to the browser. Can't you just click on the web browser? (This is a naive question, since I know little about the VM.) -- You received this message because you are subscribed to the Google Groups "sage-support" group.
