Does anyone know if there is a way to stop a python script midway?
For instance, what if I write in an endless loop into the node? is there a way to escape it without shutting down revit?
No, there is a way to write a “while” loop so that it terminates itself even if it spins out of control. Please get into a habit of putting a counter inside your loops and breaking the loop when you reach a limit. That will save you some time in restarting Revit alone…

But if you just want to stop executing the python node you could try using
import syssys.exit(0)
where 0 is whatever exit code you will exit with… this will probably bubble an exception to the python node… potentially causing a crash
I would stick to Konrad’s advice and avoid while loops when unnecessary or build escape counters into them.
Nice read Michael. Thanks for sharing!
Yes, thanks for sharing. I certainly could use “best practices” for scripting.
I do wonder if this may be some functionality that could be added. Somehow I recall that in the days of Basic & Logo (!) one could use <ctrl-G> or <ctrl-C> to stop a loop.
I think that Generative components also has a similar thing.
