Cypher UNWIND'ing and applying multiple labels to a node

Question

For a case I need to create nodes and apply defined labels to that node. The definition of nodes and labels are stored in an Excel sheet which I transform in Python with the help of pandas.

Now, I have the following code that unwinds the labels, but the problem is that the resulting node gets the literal label name 'label'.

Is there a way to apply labels to a node with an unwind?

    SET s :label)

You can't set dynamic labels in Cypher alone, however there's an APOC procedure for that, apoc.create.addLabels(). It even takes a list, so you don't have to UNWIND.
