Make a dice challenge!This is a starter activity and should take 5 minutes

[ slide 1 ]

1. Log in to your computer

2. Open IDLE

3. Copy the code below in interactive mode

1. Now place your cursor back, somewhere in random.randint(1,6)press RETURN and IDLE will copy the code for you to have another go.

>>> import random

>>> random.randint(1,6)

(After pressing RETURN, Python gives you a number between 1 and 6.)

Lesson Aims

[ slide 2 ]

Vocabularyscript mode

module

In this lesson you are going to:

1. learn how to use the randint() function

2. learn how to use if, elif and else

3. Use the input() function in some different ways

4. finish the MyMagic8Ball game

5. Run a Python file

Coding Time[ slide 3 ]

1. Find your file called myMagic8Ball.py you saved last lesson.(It should be in a Python Code folder inside Documents.)

2. Double click on the file to open it in IDLE.

3. Add the code from Code Box 3.3 (page 35) to the bottom of your file, then check it carefully.

4. Add the code from Code Box 3.4 (page 37). Check it again.

5. Save your file.

If you are waiting:

Read page 36-40 in Python Basics.

Code Analysis[ slide 4 ]

print("Welcome to My8Ball.") # get the users questionquestion = input("Ask me for advice then press ENTER to shake me.\n") print("shaking ...\n" * 4)

# use the randint() function to select the correct answerchoice=random.randint(1, 8)if choice == 1: answer=ans1elif choice == 2: answer=ans2

etc. etc.

elif choice == 7: answer=ans7else: answer=ans8 # print the answer to the screenprint(answer) input("\n\nPress the RETURN key to finish.")

Running programs in script mode[ slide 5 ]

1. Make sure the file is saved.

2. With myMagic8Ball.py open choose Run Module from the Run menu

3. The program will run in the interactive mode windowwhich now acts as a console.

If it does not work properly:

Carefully compare your code with the complete script in Code Box 3.5(page 41 and 42)When fnished:

Try out the Ideas on page 43 and 44.

Homework

1. Make a copy of myMagic8Ball.py

2. Rename it as myFortuneCookie.py

3. Using this file as a template re-write it so that it works like a fortune cookie.

Lesson Summary

[ slide 7 ]

In this lesson you have:

VocabularyWhat is a module?

1. learnt how to use the randint() function

2. learnt how to use if, elif and else

3. Used the input() function in some different ways

4. finishe the MyMagic8Ball game

5. Run a Python file

A file that stores useful functions

Can you name three ways we can use the input() function?

Answers on the last slide

What must we do to use functions from a module?import the module

The input() function[ slide 8 ]

# pause a program until a user is ready:input("Please press ENTER to continue.")

# provide a tidy way of ending a program: input("\n\nPress the RETURN key to finish.")

# get and store a user’s keyboard inputquestion = input("Please tell me your name.\n")
