I'll just add slightly to that. I used to use Pyton in my days as an 
architect because our development teams wrote their code in Java. I 
could fire up Jython and just import a new library and use the 
interactive prompt to test the new code. That was cool.

But there's another trick which is that Jython also has a compiler
so you can write a class in Python test it interactively, then
compile it so that it looks to Java like a native Java class and
Java code an use it. As an architect I could prototype ideas in
Python, and give the code for the Java guys to use. Once they
were happy they recoded it in native Java. Even more cool!
