>¿What's the meaning of that data arrange? I can't make any sense of >plotting a 2D scatter from a 3D array. when I wrote: head = [[0, 0, 10], [1, 0, 13], [2, 0, 11], [3, 0, 12], [1, 2, 11]] my meaning was to represent point of intereset with x, y coordinates and the 3rd number was height for example. I felt like I couldn't access the individual points easily, because their are located in on big list... So I wanted to have the list broken into rows, and the each row represents a value on the y axis... like this: head = [ [[0, 0, 10], [0, 0, 13]], [[2, 0, 11], [3, 0, 12]], ] But that's redundant I think now, after looking into the function zip. Maybe I could write head in the following way: # j = 0 1 head = [ [[ 0, 10], [ 1, 13]], # i =0 [[ 0, 11], [ 1, 12]], # i =1 ] But actually after understanding what zip does, I think I don't need it anyway... Talking about this: can you give me an example of another use of zip ? not just zip(*head) I did help(zip) but I could partially understand what it does. I learned more by doing: x,y,z = zip(*head) and then printing x,y,z individually. Thanks for your help so far. Oz |
