Does this look useful?

In [3]: people = [ 'Tom', 'Dick', 'Harry' ]

In [4]: ', '.join(people)
Out[4]: 'Tom, Dick, Harry'

Your confusion is in thinking about the string 'ABC' as a single
entity. For the purposes of join(), it is a sequence of three letters.
The argument to join() is a sequence of strings, not a single string.
