Question

Suppose I have

@someDecorator
def func():
   '''this function does something'''
   print 1

Now, the object func is an instance of someDecorator. Is there some way I can access the function it holds, i.e something like func.getInnerFunction().

For instance, if I need to retrieve the doc string of func().

See functools.wraps: http://docs.python.org/library/functools.html. The decorator gets the name and doc string of the original function. You use it like this:

def decorator(f):
    @functools.wraps(f)
    def wrapper():
        ....
