Part II

1 Create a variable called userChoice

2. Use the world ask user for  a number function to store the user’s choice into that variable (Note: if the user chooses a number larger than 3 or less than 1 then they entered an invalid number, something to think about

3.   Set the isShowing  property of all 3 objects to be false .  We will set the visibility to true , when the user chooses that object , later on .

Task #1

Objective; If the user chooses rock, we  need to show a rock; if the user chooses scissors, show a scissors, and the same for paper.

Use if/else and the value of userChoice  and set the isShowing  of either the rock , the paper or the scissors to true

Remember:

1= Rock

2= Paper

3= Scissors

Run through the program a few times. What should we do next ?

4.

We need to show what the CPU chooses!!

So, now we need to do a few  things:

A) edit our if/else  to consider what the user chose and  what the cpu randomly chose (both/and)

B) add a second rock, paper and scissors object that represents the CPU’s choice

(note: I set the color of the CPU’s objects to red so I can more easily distinguish the cpu’s from the user choice’s objects)

C)  Set isShowing  to false for each of the cpuChoice’s objects

For instance, if the cpu and the user both choose rock, your screen should look something like : 

5.   State who won the round or if the round was a draw :

7. The last line of your loop should ask the user if they want to play again.

Try playing the game a few times. You will notice that there is a problem, when you play multiple times

Can you see what is wrong with our current setup? The bug only applies to multiple games. If you play a single game and close Alice, you will not notice the problem.

As you can see above, when you  start  a second game, you can still see the rock and paper that were chosen in the first game.

Can you figure out how to fix  the problem?

Go here to see how to fix it and continue on with the project.

Overview: Using Python, students will use variables, input, and printing to create a Mad Lib. You will also practice designing a project by planning out your Mad Lib before implementing it. Part of the project is to use your creativity to design your own unique story.

The program will print out the title of the Mad Libs story, as well as a short explanation of game play

The program should then prompt the user to enter in nouns, verbs, adjectives, proper nouns, and adverbs

Implementation Details

Plan out your story on pencil and paper first, before you start implementing the program.

• Create your story
• Select the missing words
• Determine each words part of speech
• Create introduction
• Create questions
• Divide story into print statements

As mentioned above the program must request words from the user. The following must be included in the program:

• 10 different words inputted
• Variable names should correspond to the part of speech requested and part of the story they belong to (e.g. noun1, verb2, etc)
• You may only use 3 print statements to tell your story

Scheme/Rubric

Here’s how you get to “==” in Alice. It’s a world function. (and it must be put into an if test)

Look at the code below:

Can you see why this student lost credit :

The student did a good job using a function and storing a value in the variable, walkDistance; however, they never then used that variable .

Example 1 :

The code below is almost correct , but the variable walkingDistance  is never used by the move method !
