You should try some of the Python tutorials out there. There's a difference
between tuples and lists, and the parameter list passed to the string
formatting operator must be a tuple. String formatting will also solve your
second problem.
Also, the library reference is your friend. I particu
Dear Chris, list,
cheers for the great help: very valuable indeed.

shuffle() shuffles in place, it doesn't return the shuffled list.

Why not shuffle n directly?
n = ...
random.shuffle(n)
for x in n:
dowith(x)

Oops, I based those examples on my initial solution, not the preferred one
that preserved the questions. Here is some better code. They only use the
shuffle method, and I've elaborated a bit on the basic solution, to
illustrate some ideas for improvement.

Hello!
I like the idea of retaining my original questions by creating a proxy
list, but I wasn't able to understand (find) the proxy list:

Ooops! Missed that one, sorry.

choices = [9,2,1,3,6,4,7,8,5,0]

False

False

I would
- create the list of questions
- random.shuffle the list
- iterate over the quest

The basic approach I use in these sorts of problems is to generate the
choices, remove them from a list as they are asked, and then stop when this
list is empty.
If you don't need the list of questions afterwards, this will work:
from random import choice
questions = [ [i,j] for i in range(1

Hello everybody,
I want to create a simple multiplication trainer which quizzes me on the
multiplication table. All multiplication combinations should be asked
once, without repetition.
Here my pseudo code:
###
A = [1,2,3,4,5,6,7,8,9]
B = [1,2,3,4,5,6,7,8,9]
