How can I make two decorators in Python that would do the following?
@makebold
@makeitalic
def say():
   return "Hello"
which should return
<b><i>Hello</i></b>
I'm not trying to make HTML this way in a real application, just trying to understand how decorators and decorator chaining works.

Check out the documentation to see how decorators work. Here is what you asked for:
def makebold(fn):
    def wrapped():
        return "<b>" + fn() + "</b>"
    return wrapped
def makeitalic(fn):
    def wrapped():
        return "<i>" + fn() + "</i>"
    return wrapped
@makebold
@makeitalic
def hello():
    return "hello world"
print hello() ## returns <b><i>hello world</i></b>
