I've completed both a Python 1 and 2 class, as well as a summer camp specifically for python. I could learn more, though I'm fairly confident in what I already know.
I don't have very much experience with JavaScript, but it is something that I want to learn eventually, and have used at least a little before now.
I'm about halfway through my first Web Development class, and while I know I probably have a lot more I can learn, I'm sure I can still make something fairly competent. (This website is evidence of that.)
