Or as one might write x.remove(y) in Python:

  for demo in ("xyz", "cba", "abcdabc"):
    print repr(demo), "->", repr(demo.replace("abc", ""))

which in Python sounds suspiciously like dividend.split(divisor)

So Python's giving both functionalities in ways that are more
readable (and in the case of "-", more flexible, as you can replace
with anything, not just delete the matching content).

While subtraction and division of strings make theoretical sense, I'm
glad I don't have to think about them in my Python code ;-)
