Good so far. But you neglect to tell us Python version.

What's "this" ?  Please include real code, not just vague suggestions.

You don't show us the __init__ method.  That's where you should 
establish a "name" for the particular instance of Hand.

class Hand(object):
     def __init__(self, name):
         self.name = name
         self.hand =   something ...

     def __str__(self):
           s = self.name + " contains "
           for x in self.hand:
               s = s + str(x) + " "
           return s


When you quote an error, you should be including the whole thing, as 
well as showing the code that triggers it.  In this message you're 
giving us only disjoint fragments, and one line summary of the traceback.
