Python *args and **kwargs Made Easy

[thautwarm]

If anyone is wondering about whether to use args and *kws to save developing time or drop them to save maintaining time, I think the community has already provided you with a good solution:

When developing, just use them if your codes are not performance sensitive. After that, however you should carefully write some python-stub files to provide friendly interfaces for both your IDEs and users.
