I think @matt-bishop's answer really is an excellent one: Find a camera to borrow (or, if you must, rent) for the duration of the course, and then figure out what (if anything -- who knows, you may find you're not into photography?!) you want to buy afterward.
That said, I think it's worth expanding on this question -- perhaps even if you borrow or rent, you'll have choices to make, and want help narrowing those choices down. And perhaps you have reasons to really want to go with a purchase to start off with? :) (Though I think, really, that quote may well refer more to money, than tangible things -- but there are other risks with borrowing tangible things.)
Anyway, here are a few points that I would suggest you keep in mind:
Make certain that the camera you choose has the ability for full manual control of exposure. More than likely, your class will require this. Even if it doesn't, it's something that will really make possible a deeper understanding of photography -- not to mention giving you the ultimate control you may want (at least in some circumstances) once you've mastered the basics. In particular, you'll want to be sure that you're able to control:
Shutter Speed, so that you can have different amounts of blurring or stopping action;
Aperture, so that you can control your depth of field.
And you'll want to have the ability to control both, independently -- having neither be automatically chosen for you (at least having the ability to do this; which doesn't necessarily mean you'll always use it). If you have those controls, you'll presumably also have the ability to control Sensitivity (ISO) (or if shooting film, to have the camera aware of your choice, if you meter in-camera; see below), White Balance, and more.
Taking this control even further, having a Bulb mode would be recommended -- this gives you the ability to leave the shutter open for an arbitrary length of time, which can be especially handy if/when you do any night photography.
In any (or certainly most) modern camera(s), there will be a built-in light meter. If, though, you decide to borrow (or buy from a flea market or thrift store, or what have you) an old mechanical film camera, it's possible that you won't have one in-camera. If so (and perhaps even if not, though it's probably not worth the expense starting out unless you need it), you'll probably really want to have a light meter. There are some low-end ones (or perhaps used ones) that can be obtained fairly inexpensively. Most likely, though, you'll just have one in the camera.
While not strictly necessary, you'll very likely want to have interchangeable lenses, thus making an SLR the likely choice. This can be handy for a number of reasons, but one reason is simply that, when learning, it makes it easier to inspect the inner workings of the camera (e.g. watching the shutter open and close, or examining the aperture) (note: be careful when doing this -- there are very sensitive parts inside a camera, especially the sensor on digital cameras, that you do NOT want to touch, or perhaps even expose to the air for dust reasons. Still, I thought this worth mentioning.) Other reasons include the ability to shoot with a prime lens, which, while valuable for a number of reasons to the seasoned photographer, are valuable for the learner in part because they remove some complexity -- fewer controls to worry about, while also forcing you to pay more attention to such things as where you are relative to your subject, since you're unable to zoom in or out. It's also likely difficult (though I doubt impossible) to get bulb mode without going the SLR route.
Having the ability to have some sort of remote mechanism for firing the shutter (whether it's an infrared remote, a traditional cable release, a modern electronic cable release, or anything else that might exist) can be quite useful -- if you want to do self portraits, or when doing long exposures (to avoid camera shake).
You'll also want to think about what extra gear you might want, in addition to the camera (and lens) -- tripod, cable release/remote, light meter... I haven't mentioned a tripod before now, but it's another near-indespensible thing for night photography, and can be useful in many other situations as well. So, be sure to leave some room in your budget for one -- even if you start out with something cheap and light (which can be nice, though you may want something heavier for added stability if you start using it a lot).
There may well be other things to look at, too, but I think I've covered most of the basics. I consider point 1 to be especially important, so even if you ignore everything else, I recommend you heed that.
Good luck, and happy learning!
