Introspection to get decorator names on a method?

Question

I am trying to figure out how to get the names of all decorators on a method. I can already get the method name and docstring, but cannot figure out how to get a list of dec

That's because decorators are "syntactic sugar". Say you have the following decorator:

def MyDecorator(func):
    def transformed(*args):
        print "Calling func " + func.__name__
        func()
    return transformed

And you apply it to a function:

@MyDecorator
def thisFunction():
    print "Hello!"

This is equivalent to:

thisFunction = MyDecorator(thisFunction)

You could embed a "history" into the function object, perhaps, if you're in control of the decorators. I bet there's some other clever way to do this (perhaps by overriding assignment), but I'm not that well-versed in Python unfortunately. :(
