Ezio Melotti <ezio.melo...@gmail.com> added the comment:
You forgot to use raw strings:
>>> text = "The cat ate the rat."
>>> print("before: %s" % text)
before: The cat ate the rat.
>>> text = re.sub("(\w+) ate the (\w+)", r"\2 ate the \1", text)
>>> print("after : %s" % text)
after : The rat ate the cat.
>>>
(Maybe you should reconsider writing yet another tutorial about regular
expressions, and possibly submit patches to improve the official regex howto if
you think it's not good enough.)
