Okay now let's add the others to the beatles.

Okay now let's add the others to the beatles. Can you please use the method on lists that allows you to add all values from one list to another?

beatles.py 
beatles = ["John"]
beatles.append("Paul")
others = ["George", "Ringo"]

The challenge actually gives you the answer in the debugging. This problem requires you to use the extend-method on the lists. I went for the easy solution of just doing the following.

beatles = beatles + others

Which works, but it's not what the challenge wants. The solution that gets accepted is the following on.

beatles = ["John"]
others = ["George", "Ringo"]
# Your code here
beatles.append("Paul")
beatles.extend(others)
