TypeError: expected int, got list

I search the forum but couldn’t find the answer.
Why is this happend?

@jw.vanasselt that is one long script, not sure what you are doing, if you can provide a small Revit sample file to test your code, it would be better; Nevertheless, based on the error you posted, maybe a zip to loop at the same time over 2 different variables might solve your problem, try it likes this:

for pf, i in zip(pipe_fitting, ukeys2):

Thanks! This is a solution to do this.
I found this solution too:

#toevoegen van sections aan bochten
n_section = []

uk = 0
n_section = []
for pf in pipe_fitting:
	uk += 1 	
#Einde transaction

@jw.vanasselt yep, basically it is the same, instead of looping over items, you are getting the items by accessing the list through their indices, and incrementing the indices to loop over the items.

Hi @tradelie ,

I have in another script the same error but my list is deeper.
How can i use this method:

It’s about this forum:
