I would expand that to "If you learn to program in one language, it's easy to learn another within the same paradigm".
If you know Python, Ruby or PHP will be pretty easy for you to pick up. You might have some difficulties with Haskell and Lisp.

Learning some Haskell was probably the most worthwhile time I have spent learning a language because it forced me to fundamentally reevaluate how I think about programming. Now I don't use Haskell at work, and likely never will; but, years later, the techniques I learned from it I still apply daily when I write C, Python, JS or whatever. It made my code far cleaner.
