assistance with python coding

[Richard Morello]

Dear John,
 
This is a switch.  In other words if you have two variables, a and b, switch
the values.  The author of the exercise is trying to point out that without
the sequence operation, you must do it the same way as in nearly all other
languages.  That is:
 
tmp = a
a = b 
b = tmp
 
Python gives you the ability to switch two variables with just a single
statement.  To perform the above with a sequence assignment would be:
 
a, b = b, a
 
Your example only slightly complicated this by using an array.  The answer
you are looking for is:
 
tmp = self.cards[i]
self.cards[i] = self.cards[j]
self.cards[j] = tmp
 
Let me know if you need any more help!
 
Yours truly,
Richard Morello

I don't understand what this question is asking; can you clarify for me and
maybe point me in the right direction?
 
As an exercise, rewrite this line of code without using a sequence
assignment. 
self.cards[i], self.cards[j] = self.cards[j], self.cards[i]
