So you've probably added your own pyscript button before to a node, but in case you haven't, here's how you can do it... aaaand because your time is valuable, and we're all about speed here in comp, here's how you can do it faster! :D
0:00 - adding a knob
1:40 - it's just a text blob
4:19 - let's edit a knob from the script editor
6:00 - progressively making the 'rig'
11:05 - gotcha! get your imports right :|
oh, by the way... https://en.wikipedia.org/wiki/Duck,_d...
