nulis | Tree editor for writers | Frontend Framework library

General problem: Using the elements of some list of length m*n, create a list with m sub-lists, each of length n.

In my case, m > n, and are 10 and 3 respectively.

The final output should be a list ("lis1") containing ten lists (the iterations of "nulis") with three elements each. Also, my current algorithm should leave "lis0" empty. The error is returned right at the last step.

I am parsing some CSV files (four columns - one with a list of 3 numbers, three with one number each about the respective lists) I generated using the CSV module. I couldn't figure out how to do this more elegantly reading the module's documentation and am having some trouble with the last step: recombining the terms in the list-columns into 3-element-long lists (the other columns are done).

The solution/explanation would be ideal, but I'll take an alternative approach if you've got one.

I can't remember some of the others, but I had tried using "for j in list: while (j == list[list.index(j)+1]) or (j == list[list.index(j)-1]): newlist.append(j)" but got memory errors. Solution for that would be sweet though not as pertinent because it would only work for a special case of what I'm looking into (one which works because of an inadequacy in another script I was writing). In the current version, I have tried to 'break' (concludes a step early but there's an overlooked error of the same type), 'continue', and 'pass', to no avail.

edited script into a function which gives the same error, feel free to give the special case (i.e. any solution to the problem outlined above with m=10, n=3)
