Python Development Techdegree Student 892 PointsStruggling with Beatles
"Okay now let's add all of the items in others list to the beatles list. Can you please use the method on lists that allows you to add all values from one list to another?"
beatles = ["John"]
others = ["George", "Ringo"]
last_one = ["Paul"]
beatles.append(others)
beatles.extend(last_one)
beatles.extend(others)
What's wrong?

Be sure to add it on only one time, using the correct method.

231,269 PointsNotice that you're putting one entire list inside the other as a single element. That's an indication that the wrong method is being used.
Be sure to "use the method on lists that allows you to add all values from one list to another".
