After spending hours messing around with StringVar and lambda functions, this showed me within the first three minutes how I was overcomplicating a simple button. Thank you and thanks again!

Excellent way of teaching, animation makes the concept more clearer and easy to remember.

Very informative, and thank you for the info. That music at the beginning, though. I thought I was getting a PSA from 1992

Thank you for this. I was struggling with updating an image in a GUI. Changing the image by changing the label causes flicker.
But using this method to dynamically update the image without recreating the label means the image can now change without any flicker.

I get an error nonetype object does not support item assignment
Why is it so?

Hello Philip, for what practical reason could one want to change dynamically a Python tkinter label? I fully understand your excellent explanation, but this somehow is not clear to me :)

So, how do I change the text size?

Like, the actual size of the writing

Viewers might find useful "Capture2Text" as this allows a screen capture of a paused video and then converts the text selected; into your clipboard, that can then be pasted in idle for correction of any errors and run.

Is it possible to use this process with if statements to change a polygon on a tkinter window depending on a count? I'm trying to draw a simple interface for my Masters project and am at an impasse with this point. Basically I want a polygon making an arrow pointing (effectively) N S E and W along with a stop. When a blink event from a headset is triggered I want a count to cycle the options and then the tkinter window to redraw the corresponding direction but currently all i am getting is the "startup" window. I'm not a novice to coding but am new to python.

I've got pretty much everything else sorted out but obviously this point is the crux of the whole system.
