<do not remove the three backticks above> animals = ["aardvark", "badger", "duck", "emu", "fennec fox"] **duck_index** = animals.index("duck")# Use index() to find "duck" animals.insert(**duck_index**, "cobra") What is the purpose of adding **duck_index?** Even in the second part I know we are inserting cobra however, why is there a need for duck_index in the second function? print animals # Observe what prints after the insert operation
