No problem but don't overuse the underscores.  It starts to look like
Perl.  The parameters to the methods and the local variables in the
methods will not pollute your namespace.  The only area you need to
concern yourself with is module level object references.

 >>> import mymodule
 >>> print dir(mymodule)

that's the list you need to be concerned with.  You will see that a lot
of names are already private.  In the case you present I don't think
that anything there was private that is not already private based on
what it inherits from object.

This is the number one lesson you should take to heart from this.

And you don't want to.  The test cases should make sure that public
objects and methods act as specified.  That's what allows you to
refactor any time you want.
