   string.split() produces list.

   There is no list.join() because list is only one of many containers.
Should tuple has its own .join() method? What about other containers?
iterables? generators?
   string.join() can accept any iterable, not only a list. That's the
explanation why it's preferred.

   In what way do you expect list.join(string) would help?
