Excuse me for the incomplete info previously.
If I call it with
a = f(3)
the result is 12. It is correct as below message. That is no use of *args
and **kwargs.
If I put more parameters in f, it will give errors as below.
///////////
%run "C:/Users/pyprj/ipython0/decor0.py"
f was called

TypeError Traceback (most recent call last)

----> 5 return func(*args, **kwargs)
6 return with_logging
7
TypeError: f() takes exactly 1 argument (2 given)
%run "C:/Users/rj/pyprj/ipython0/decor0.py"

I don't see *args and **kwargs can be used by other way yet.
Do you think this internal function definition (with *args) is useful?
Thanks,
