You've already got self in the __str__ method, or you wouldn't have
access to self.hand. But there's no characteristic of 'self' that has
any idea of a name like "dealer" or "player". You have to add that if
you want it, as I suggested in my first guess. Steven has shown you as
well, along with a better explanation.
An object does NOT know the name or names that may be bound to it, any
more than I know what page of the county register has my birth
certificate recorded. If I want to know my own name, I'd better
remember it. Along with any nicknames I want to respond to. The way to
do it is the same way to know the hand that I hold, make an instance
attribute. And the place to do that is in the __init__() method.
def __init__(self, myname):
self.hand = 
# create Hand object
self.name = myname
s = self.name + ' contains '
for x in self.hand:
s = s + str(x) + " "
