  You don't.  See below

I haven't looked at what the code is trying to do, just a cursory scan to fix 
#1 for you.  

You want to make sval a part of the object state (ie.  It stays with the 
object, and can be used in other member functions).  To do this, you refer to 
it as self.svals, not just svals.  The first adds it as a member of the 
object, the second declares it a local variable, which goes away when the 
member function returns.

So, as a first step, change all the svals to self.svals.

Then, since pos doesn't exist in the down() member function, change that too. 
 I think you meant to use 'i'.  In any case, the self.svals thing will get 
you started.
