[Tutor] Having trouble with a component of the random module

I shouldn't get the same card twice in the same batch, no.
Of course, in separate trials, I may get the same card again.

Basically, I type the names of relevant cards in a list, and proceed  
to "tell" my program which list to read, and how many cards to pick  
from that list.

Normally, I put each card name in the list only once. But if I type  
the same card name twice, the program sees the repetitions as  
different entities, and may display both of 'em if the randomness  
works out that way.

random.sample I think runs dependent trials (the first pick affects  
the odds of the second pick, etc.) - kind of like pulling tickets from  
a hat.
This is as opposed to independent random trials a la dice rolling.

Someone correct me if I'm wrong on this - for this application, I want  
dependent trials.
