Lists

What students will learn:

$1)$ Declaring lists

$2)$ Performing common operations on lists

Overview: Lists are an incredibly powerful thing in computing. Almost every audio file, video file,

and image you$$ve ever seen on a computer is stored in a list$-$like structure. A list is simply a

data structure that holds a lot of values. For example, they could hold $50$ integers, $100$

Booleans, or a million floats.

Assignment $6$A: Keeping Score. Now that we know about lists, we can keep track of when

events occur during our program. To prove this, let$$s create a game of Rock$-$Paper$-$Scissors.

For those not familiar with this game, the basic premise is that each player says $$Rock$-$Paper$-$

Scissors!$$ and then makes their hand into the shape of one of the three objects. Winners are

determined based on the following rules:

Rock beats Scissors

Scissors beats Paper

Paper beats Rock

At the start of the program, it will ask the player how many rounds of Rock$-$Paper$-$

Scissors they want to play. After this, the game will loop for that many number of times.

Each loop, it will ask the player what item they want to use $$ Rock, Paper, or Scissors.

The computer will randomly generate its own item, and a winner will be determined.

The game will then save the result as an element of a list, and the next round will begin.

Once all the rounds have been played, the program will say $$Game Over$$ and display a

list of who won each round, in order.

Hints: While the random functions we$$ve discussed thus far can$$t generate words, we

can associate numbers with them instead. For example, we might treat the computer

randomly generating $0$ as if it threw Rock. We could then use that number to access a

predefined string list with $$Rock$,$Paper$,$ and $$Scissors$$ stored inside it$.$

Sample Output #$1$:

How many games do you want to play?: $3$

Round $1$: What do you want to throw?: Rock

Computer threw SCISSORS!

Round $2$: What do you want to throw?: Paper

Computer threw PAPER!

Round $3$: What do you want to throw?: Rock

Computer threw PAPER!

Game Over...

Here$$s the recap:

Player won Round $1$ with Rock

Tied on Round $2$ with Paper

Computer won Round $3$ with Paper

Sample Output #$2$:

How many games do you want to play?: $2$

Round $1$: What do you want to throw?: Scissors

Computer threw ROCK!

Round $2$: What do you want to throw?: Paper

Computer threw SCISSORS!

Game Over...

Here$$s the recap:

Computer won Round $1$ with Rock

Computer won Round $2$ with Scissors
