Calling a function or method by name

I don't even know where to look for the answer to this one. If I have a
function name, stored in a string, how do I call that function? I have a
feeling it has something to do with apply() and __dict__, but I don't know
how to start looking.
In particular, if I have a class with several subclasses, and I want to call
a method, how is that done?
What is this for? Well, I want my class to respond to keys being pressed.
Each key will trigger a call to a class method with no arguments (except
self). I don't want to have a huge if/elif structure because that is slow. I
want to use a dict. The keys will be the value of the key being pressed. The
values will be the name of the function to call.
Any help would be greatly appreciated.
