comment Animator not always working under 10.0/1
I think there was such an error, I saw it on one or 2 of my demos. But now it is gone, at least I tried your code in 10.1 and it works with no problem on my windows 7. But the error message you show, I've seen before and even reported it. I had no idea why it came from. Code used to work ok before 10, and then on some demos I saw the above message.

comment Create an array with certain conditions and use it to fill a matrix
You mean you want to translate power_spectrum_k = np.zeros(n, float) to Mathematica? I would use Table command, as in Table[0,{n}], for the whole thing, may be n=10; Table[Exp[-(2 Pi k w/L0)^2], {n}] ps. why not use ^2 instead of writing the same expression 2 times?

@belisarius thanks for the link. I had no idea human can make sound with such low frequency.

comment Why does a comma insert a line break in a comment?
yes, turning off line breaking, will make big mess of the code formatting? is it like writing in a code cell basically, instead of input cell. I think. Never tried it. But the second option you show is not really practical. Having to keep pressing ESCnbsESC each time one wants to make a , or ;. These are comments, and they should just be written freely and as is. This problem should be fixed at the source by WRI.

how did you figure how to call it with no example given? very good. But I see no DO LOOP in your answer like the teacher code? ;)

comment Plot roots of polynomial system of equations in 3 variables
@user27616 I am not following you exactly, but there are lots of Contour related functions in Mathematica, and also options to control what they show and how. If you have problem or question with specific implementation or how to use it, it would be better to post that as separate question.
