Is there a way to gracefully exit early from a Python node, if, for example, an error is encountered? In a script one would use sys.exit, but that gives a stack trace in the console, which might obscure any log message written about the error.
Hi @ccdc_knime,
There is no similarly simple way that I know of. You could put your entire script into a function and add a call to that function at the end of the script. Inside the function you could then return
early. So something like:
def my_script():
# Do stuff
if error:
# Exit early
return
my_script()
I like the idea of using sys.exit
the same way in Python nodes. I will add a feature request for KNIME to gracefully handle SystemExit
exceptions as a way to terminate script execution early.
