python decorator with arguments of decorated function

Question

When I wrap a function with @, how do I make the wrapper function look & feel exactly like the wrapped function? help(function) in particular.<

Answer 1

I think the other answers are preferable, but if for some reason you don't want to use an external module, you could always alter your decorator like so:

def wraps(f):
  def call(*args, **kw):
    print('in', f, args, kw)
    return f(*args, **kw)
call.__name__ = f.__name__
call.__doc__ = f.__doc__
return call
