Hello, guys! ... First of all, I'm very new to sage and this forum, so please be generous for my question, please...
So, I've wrote in sage (between @@@@@'s):
Then, the result for p and q was
p=[2,3,1] and q=[2,3,1].
But, what I actually want is that p doesn't change; so I want to have
p=[3,2,1] and q=[2,3,1]
so that p doesn't get changed when we set 'q=p', while q is defined to be p when we set 'q=p' and then q get changed via the codes followed by 'q=p' above... In other words, is there a way to 'overwrite' q to be p, and not changing p? Thank you!!!
