Python decorator handling docstrings

Question

I have a problem using docstrings with decorators. Given the following example:

def decorator(f):
    def _decorator():
        print \'decorator active\'
           


        

Answer 1

I found a solution, but don't know if it's really nice:

def decorator(f):
    def _decorator():
        print 'decorator active'
        f()
    _decorator.__name__=f.__name__
    _decorator.__doc__=f.__doc__
    return _decorator

The part with _decorator.__name__=f.__name__ seems a little bit hideous... What do you think?
