It's spectacularly useful, and I personally really love using it - but to say it's an industry standard the way C or C++ are is to stretch the point a wee bit too far unfortunately.

Still though, we use some languages for teaching (like Pascal or Modula-2) which don't have the kind of industrial usage levels of C or C++, so we might see Python being taken up sooner rather than later. I think there are one or two courses already using it over here on a trial basis.
