AttributeError: 'NoneType' object has no attribute 'set' (Tkinter)

Question

I am trying to use tkinter (by following a tutorial, I am learning) to create a simple text editor. Here is the code that I am having issues with:

scroll = Scrollbar(stimulator_window).pack(side=RIGHT,fill=Y)
Editor=Text(stimulator_window,width=400,height=450,yscrollcommand=scroll.set).pack(fill=BOTH)
scroll.config(command=Editor.yview)

And I am getting this error:

Editor=Text(stimulator_window,width=400,height=450,yscrollcommand=scroll.set).pack(fill=BOTH)
AttributeError: 'NoneType' object has no attribute 'set'

Does anyone have any idea why this is happening?

`scroll` is `None` because that is what `pack()` returns. – quamrana Aug 06 '22 at 19:20 — quamrana, Aug 06 '22 at 19:20

You meant to use two lines:

scroll = Scrollbar(stimulator_window)
scroll.pack(side=RIGHT,fill=Y)

Now this returns "AttributeError: 'NoneType' object has no attribute 'yview'" – fox tech. Aug 06 '22 at 19:27
That's a new question, but it has the same answer. – quamrana Aug 06 '22 at 19:29
