luofeiyu: please take care to include the attribution line. The text above is 
from Ian Kelly, but you do not show that. Attribution is important: it both 
gives credit and also lets people know who said what.

Well, I'd not do it that way. I would just make .grow() not return self.res.

Basicly, if a function returns None (which it does when it does not have an 
explicit return command), the python interpreter prints no output. So I would 
just write .grow() like this:

     def grow(self):
         self.res=  a data ananlyse process

Let the caller access self.res directly afterwards if they want to.

For Ian's suggestion, write a trivial method like this:

   def grow_but_be_silent(self):
     self.grow()

Cumbersome, but it would do what you seem to ask for.
