SopNode object is not iterable - python

[MatDuf]

Hi! I have a problem with what strikes me as a simple task.

 

I made this simplified test setup (see image): 4 boxes in a geometry node all going into a merge node.

 

I select the merge node and run the following python script from a shelf tool (Don't bother about the purpose of this... This is only to show my problem):

 

myMerge=hou.selectedNodes()[0]
toDel = []
myBoxes=list(myMerge.inputs())
print(myBoxes[0])
toDel.extend(myBoxes[0])

This will fail at the last line that is supposed to add a single member of the myBoxes list to the toDel list. It throws the error in the second image. What bothers me is that the print statement works appropriately but for some reason, the same structure doesn't work to add the item to the list.

 

Am I just missing something??

 

Thanks!

The extend function expects an iterable as it's argument. myBoxes[0] returns the SopNode object, rather than an iterable.

 

You either need to change it to something like this:

toDel.extend([myBoxes[0]])

or probably better to use this:

toDel.append(myBoxes[0])

My mistake...! Thanks Dannio!
