Hello, I am wondering if can do this:
Let say I have a list of lists. Each individual lists have a bunch of elements. Now I would like to either get or set the first element of each individual list. I could do a loop and/or list comprehension, but I was wondering if it was possible with something like: aList = [ [1,1,1], [2,2,2,], [3,3,3] ] aList[:][0] = 10 If I print aList[:], I get the list with the nested sublists. >>> aList[:] [[1, 1, 1], [2, 2, 2], [3, 3, 3]] But as soon as I introduce the [0], in an attempt to access the first element of each sublist, I get the first sublist in its entirety: >>> aList[:][0] [1, 1, 1] I would have hoped to get something like [1, 2, 3] Is this possible at all?
