How can i do this?

I don’t understand. im stuck beacuse i dont know about 2D dimensional lists. AND ITS TO HAAARRRDDD TO DO!!!:

last_semester_gradebook = [[“politics”, 80], [“latin”, 96], [“dance”, 97], [“architecture”, 65]]

Your code below:

subjects = [“physics”, “calclus”, “poetry”, “history”]
grades = [98, 97, 85, 88]
gradebook = [
[“physics”, 98],
[“calculus”, 97],
[“poetry”, 85],
[“history”, 88]
gradebook.append([“computer_science”, 100])
gradebook.append([“visual arts”, 93])

here’s an example:

list2 = [
  ['a',  'b', 'c'],
  ['d',  'e', 'f'],

this is a list of lists, which is a 2D list.
If I wanted to access 'b', that’s in the first list (so index 0 within list2),
and ‘b’ is the second thing in the inner list, (so index 1),
so I would do
list2[0][1] to get the 'b'

If, in the last list, I wanted the last item.
I would do
list2[-1] gets you the last list
and another [-1] gets you the last item of that list.

So you’d use


to get that 88
because its in the last list (within gradebook), and its the last item of that list.

Also, check your code for any spelling errors.
