say you have a list:
list = [1,a,2,b,3,c,4,d,5,e,6,f,7,g,8,h,9,i,10,j,11,k,12,l,13]
What's the easiest loop set up if I want to store each number (every other slot) into another list? The above list is actually text from a file read and then split with "1 a" and such on each line of the file. After I do that, I want the other slots put into another list. Also, let's say the above letters are different and there are multiples of the same letter, I want to delete the multiples and be left with a list of all the unique letters in the original list.
Ex: if the list is [1,a,2,a,3,v,4,t,5,v,9,c], I want [1,2,3,4,5,9] and [a,c,t,v] (numerical and alphabetic order respectively)
