Join Barron Stone for an in-depth discussion in this video Multidimensional lists, part of Programming Foundations: Real-World Examples.
- Basic lists are fairly easy to understand…because they're just a simple sequence of items.…However, things can get a bit more complicated…when we embed lists inside of other lists…to create two-dimensional or even three-dimensional lists…which can be a bit harder to visualize.…That's one of the reasons I like to think of objects…in a list as cars in a parking lot.…To index my car in a two-dimensional parking lot,…I need to know two pieced of information.…First, I need to know which row I'm parked on…and then I need to know…at which spot along that row I parked.…
The same concept can be extended…to three-dimensional lists of lists of lists…and that's like a multi-story parking garage.…To index my car in there, I need to know three things.…First, which floor I parked on.…Next, I need to know which row on that floor I parked.…And finally, which spot along that row, on that floor,…I'm parked in.…Now, my analogy has to end here because…a four-dimensional parking lot doesn't exist in real life…but software lists don't have to stop…
