Wow that's a decent set of third party packages.
What kind of software do you develop with all that?
Besides standard library I use only pygresql.
... and "eric 3" IDE for developing.
Do you use Boa IDE?

I see that python finds more and more applications in different areas.
Do you think it might become a universal language?

I've heard a lot about Boa, but never used it.
Is there refactoring capabilities and/or unittest?
I use 'eric3' for big projects and 'vim' for small

Well, what I ment is "absolutely universal", so that any application could be written in it.
There are still some areas where python can expand in the future:
1) performance-critical applications and libraries (lapack, blas)
2) kernel programming
3) drivers (I guess certain drivers might be in python)
If anybody will write an efficient python compiler it would be possible  to write almost every application in pure python.
I think that python may also replace javascript in internet browsers sometimes ...

Of course, refactoring is just a big word for that.
In most IDEs refactoring is just an ability to correctly rename a variable (as well as a function, an attribute or a method) so it will be automatically renamed in all the files of the project. This kind of functionality  is different from "replace" because it understands the scope of variable (thus it would not rename other variables with the same name but different scope). It's quite convenient sometimes.

I too heard that Boa is interesting
