In the code you posted above, the extend function will do nothing! Just with the functions above it, you have to give it a parameter for it to do its thing. Pass it an iterable (eg, a list), and it will tack what you pass it onto the end of iterable you've called it on.

list_1 = [1, 2, 3]

list_1.extend([4, 5, 6])

print(list_1)

... will print out [1, 2, 3, 4, 5, 6]
