This produces different results from the original, though.  Not clear
to me if the specs include producing exactly the same results as the
original, but, if so, then:

  temp=self.cards[j]; self.cards[j]=self.cards[i]; self.cards[i]=temp

might be the kind of approach the exercise's author had in mind.
