This is a very good point. The Pythons may actually be beneficial. Preying upon Felis domestica for example. Juvenile Pythons are a beneficial food source for others in the ecosystem.

It is generally agreed that they are established in a subtropical no-man's land of preserves in South Florida, but establishing sustainable populations further North is wild speculation, at best. It certainly has not been proven.

And as far as the Python's being injurious where established, all things considered, that has not been proven either.
