Image 1 of 1: ‘veg is represented as a shelf full of produce. There are three rows of vegetableson the shelf, and each row contains three baskets of vegetables. We can labeleach basket according to the type of vegetable it contains, so the top rowcontains (from left to right) lettuce, lettuce, and peppers.’

Image 1 of 1: ‘veg is now shown as a two-dimensional grid, with each basket labeled according toits index in the nested list. The first index is the row number and the secondindex is the basket number, so veg[1][3] represents the basket on the far rightside of the second row (basket 4 on row 2): zucchini’
To reference a specific basket on a specific shelf, you use two
indexes. The first index represents the row (from top to bottom) and the
second index represents the specific basket (from left to right).

C gets printed because the first two conditions,
4 > 5 and 4 == 5, are not true, but
4 < 5 is true. In this case only one of these conditions
can be true for at a time, but in other scenarios multiple
elif conditions could be met. In these scenarios only the
action associated with the first true elif condition will
occur, starting from the top of the conditional section.
This contrasts with the case of multiple if statements,
where every action can occur as long as their condition is met.
