Its iterable object support is more than godly... It saves so many lines of code and closes possibilities for programming errors too. Also, the library is so impressive and feature-laden (although not as much as Java). XML-RPC support by default? Hell yeah, I'm down with that!
Being an interpreter language is a big plus too. I can actually
play with library classes on the command-line interpreter before using it in my program. :)
