The actual command of RemoveItemAtIndex only works with a single index. Nodes can be built to accept lists as it treats each item in the list as a separate RemoveItemAtIndex command, but in Python, it will not do that automatically. You will have to create a for loop. There are better ways to do this in python though.

def tolist(obj1):
	if hasattr(obj1,'__iter__'): return obj1
	return [obj1]

def removeindex(elements, index):
	ran = range(0,len(elements))
	lst = []
	for e, r in zip (elements, ran):
		if r not in index:
			lst.append(e)
	return lst


elements = tolist(IN[0])
index = tolist(IN[1])

rev = removeindex(elements, index)			

OUT = rev
