You are going to have to tailor the script to iterate over the input and decide what format that is going to be - say integers or elements

# Check for list
if not hasattr(IN[0], "__iter__"):
    IN[0] = [IN[0]]

# Id integers
stairs_run_elements = [ElementId(item) for item in IN[0]]

# Selected elements
stairs_run_elements = [item.Id for item in UnwrapElement(IN[0])]

Modify parent_stairs.extend(stairs) line as extend is used to join a list (or other iterable) to a list

parent_stairs.append(stairs)
