This solution can handle a list of authors of length > 0, though it can be modified to handle 0-length lists as well. The idea is to first create a format string that we can format by unpacking list. This solution avoids slicing the list so it should be fairly efficient for large lists of authors. First we concatenate for every additional author beyond two authors. Then we concatenate if there are two or more authors.
