问题 I'm trying to do something in a Jupyter notebook that runs a continuous process, but with a pause button to interrupt it. Below is a simplified version of what I've done so far, but it seems Ipython wants to complete the entire run() function before it executes commands it receives from the button. The problem, of course, being that run() will never finish unless interrupted. Interestingly, the below strategy works just fine in my Tkinter frontend so long as I put a pause(0.0001) at the end
