dealer=Hand()

This prints out 'Hand contains " foo bar

Is there a way to include "self" in the __string__ so it reads
Dealer hand contains foo bar
Player hand contains foo bar
No, you can't. You're assuming that the name bound to an object is
somehow part of that object, but it isn't. What would happen if you
did this:
print(Hand())
There's no name, so you can't get that information. The only way to do
it would be to pass that to the Hand object, but you may as well
simply print it out separately.
It is very useful for a Hand instance to know its "name".
Lots of game strategies treat a collection of such objects identically,
and then after the fact want to tell them apart. Printing is one
example. But if you've just concluded that object 174fa44 is the
winner, it'd be nice to be able to tell the user in his own terms.
As you say you shouldn't attempt to guess it, but should pass it into
the initializer.
