Yes, something like that. If you are proficient with the acoustic guitar, you'll probably be able to pick up an electric for the first time in your life and play.

On the other hand, if all you've ever played is an electric (with its low action and lighter strings), playing an acoustic will probably require some time getting used to.

I would compare electric to something like Python and acoustic to C :)

The difference isn't really as big as that. It'd be like starting with Perl and then moving onto Ruby or Python.

I would say its like starting with Python and moving to JavaScript. It really isn't that much more difficult.
