I'm going to be brutally honest, and simply say that this is terrible
code. I'm not even going to _try_ to fix it. Instead, here's a
completely rewritten form:

def checkexception(func, *args, **kwargs):
    try:
        result = func(*args, **kwargs)
    except BaseException as e:
        print("Exception raised: %s" % e)
        try: print(func.__doc__)
        except AttributeError: pass
        raise # Let the exception keep happening.

But really, there are even better ways to do this. Just let the
exception happen, and then use something like ipython to help you
analyze the traceback.
