You can use/add a while loop as shown

On Linux, you need to capture packets on the loopback interface. On Windows, you have to install Npcap and select the Npcap loopback interface. AFAIK Npcap comes with the Wireshark installer.

Not sure if you need to be root (on Linux) or Administrator (on Windows) to capture traffic.

You have created two instances of StartPage, one inside App.__init__() (frame = StartPage(container)) and one in the main code (s = StartPage(app)). The bindings are on the second instance but it is not shown. The canvas.move() is working but you cannot see it.

Change s = StartPage(app) to s = app.frames[StargPage] will solve the problem.

I think you might want to refactor your code a bit and wrap your querySelector's in an onload event listener because (at least for me) the variables are all undefined. You should wait until the content (class names etc.) are already rendered onto the DOM.

Then you need to wrap your point check in a function that gets called at the end of your point assignment. Otherwise the check will only be called when the JS file initially loads. I put the point evaluation in the evalPoints function and added it at the end of the point assignment function so that so the check gets run every time you add a point.

You also don't appear to have resetScore declared anywhere so I added that as well.
