In the Dungeon Game, Kenneth mentions that CELLS could be a tuple instead of a list of tuples. What would it look like?

Does he mean it would be something like (x, y) with x and y being variables?

Hi there, yes the cells could look like the following

```CELLS = [(0,0),(0,1),(0,2),
(1,0),(1,1),(1,2),
(2,0),(2,1),(2.2)]
```

Hey Stuart, that's a list of tuples, I was more wondering what it would look like as a tuple since Kenneth mentioned it. Could CELLS look like:

```CELLS = ((0,0),(0,1),(0,2),
(1,0),(1,1),(1,2),
(2,0),(2,1),(2.2))
```

and what would be the difference?

Yes, you can have a tuple of tuples as you have highlighted above. I am no expert in Python but I dont this gains you much over a list of tuples.

One thing maybe of benefit is that Tuples are immutable (cant be changed) therefore given that we have fixed set of cells, using a Tuple means that we could not inadevertenly change something., Also tuples are meant to perform better than lists....

I tried myself to use tuple instead of list. It actually makes sense because that should be a immutable. We don't want to change the CELLS. It's supposed to be constant. I've seen `random lib sample` works with tuples as well. from the docs: `random.sample(population, k)` for instance if you feed a dictionary to the `random.sample` you get an error:

Population must be a sequence or set

So your

```CELLS = ((0,0),(0,1),(0,2),
(1,0),(1,1),(1,2),
(2,0),(2,1),(2.2))
```

makes total sense, just that the final cell has a `float` in it instead of a `tuple`
