FORCE A RETURN OUT OF A PYTHON NODE

[DougStruthers]

As Python frowns on goto lines, I am looking for a way to break out of a python script.  

return does not appear to work though I found an old 2013 suggestion.

There are many different ways to do it in Python and HOM. You can wrap into a function and use returns in the body. Or raise descriptive errors and treat them differently. HOM has all sorts of custom errors too.

This one will cook a node without errors. Depending on the input, it may show a warning and stop the script from executing further:

node = hou.pwd()
geo = node.geometry()
pts = geo.iterPoints()

if not pts:
    raise hou.NodeWarning('Input geometry has no points.')

geo.addAttrib(hou.attribType.Global, 'number_of_points', len(pts))

the easy solution is to wrap the entire node of the sop in a function, like f1 already suggested

def myfunction():
	print "print this"
	return
	print "but not this"

myfunction() #make sure you actually run your code at the bottom of course
