Python: the While loop at the end keeps generating a new random card, how can I get it to generate once and stop?

The code below is skeletal, it is supposed to be the beginning of a card game. I generated a random hand (1 card for now) but I can't seem to get it to only generate the first hand once. The while loop repeats and constantly generates a new random card for the first hand. Thanks in advanced, first time poster so I'm sorry if this is all formatted terribly.
