⏱️ DO IT NOW

Create a OneNote Page and copy this into the title:

Lesson 5-6 - Spring 2 - Functions and RPG

Sign In with your Microsoft Account
Create a New project and call it Y8 - SP2.5-6 - Functions and RPG
Rename main.py as DIN.py
Share a link to your project on the OneNote page
In VSCODE, write code that will result in the output below⬇️⬇️

Name the capital of Iceland: Rekjavik

Correct, the capital of Iceland is Rekjavik

🎯 Learning Objectives

LO1:We will be able to use selection, input, variables and outputs within our programming
LO2:We will be able to explain how functions enhance the nature of a program
LO3:We will be able to create a program that incorporates the use of functions

📖 Everybody Reads

Functions are reusable blocks of code (similar to the concept of a template)
Because functions are reusable we don't need to write the same code repeatedly
Each function can be called into action at any point in a program
Each function can be called into action more than once in a program

Coding Functions (1)

Create a new file in your VSCODE project
Call it Activity 1.py
Add the code below to it ⬇️⬇️

#------------------- Functions-------------------------
def kenya():
    question = input("What is the capital of Kenya? ")
    if question.lower() == "nairobi":
        print("Correct")
    else:
        print("Incorrect")

Try to run the code
Does anything happen?

Coding Functions (2)

Now Add the code below to it ⬇️⬇️

#------------------- MAIN PROGRAM-------------------------

print("The program will now ask you a question")

kenya()

Try to run the code again
Does anything happen?

⌨️ Independent Challenge

Here is a new function definition
See if you can work out where to put it


def adding():
    num1 = 8
    num2 = 9
    answer = num1 + num2
    print(f"{num1} + {num2} = {answer}")

Here is a call for the function
See if you can work out where to put it


adding()

Only click this if you get really stuck!

#------------------- Functions-------------------------

def kenya():
    question = input("What is the capital of Kenya? ")
    if question.lower() == "nairobi":
        print("Correct")
    else:
        print("Incorrect")



def adding():
    num1 = 8
    num2 = 9
    answer = num1 + num2
    print(f"{num1} + {num2} = {answer}")


#------------------- MAIN PROGRAM-------------------------

print("The program will now ask you a question")
kenya()

print("This will add two numbers together")
adding()

📝 MWB Reflection Task

Open the mini-whiteboard app in a new tab

Your teacher will start with these leading questions:

Where do function definitions go?
What must we do in order to run a function?
style="user-select:all; cursor:pointer;" >How many times can you use a functionin your code?

RPG CODE

Create a new file in your VSCODE project
Call it RPG GAME.py
You will now develop more functions to create new levels in this game!
Notice how one function can be called within another
Firstly, run it to see how it works!

# Hallway
################################################

def hall():
    print("")
    print("You are in the hallway")
    print("Where would you like to go?")
    print("(1) Room 1")
    print("(2) Room 2")

    choice = input("Enter your choice: ")

    if choice == "1":
        room1()
    elif choice == "2":
        room2()
    else:
        print("Invalid choice - back to the hallway")
        hall()


# CODE FOR ROOM 1
#################################################
def room1():
    print("")
    print("You are in room 1")

    # ADD CODE FOR ROOM 1 HERE
    
    print("Type h to go back to the hallway")
    choice = input("Enter your choice")
    if choice.lower() == "h":
        hall()
    else:
        room1()



# CODE FOR ROOM 2
################################################
def room2():
    print("")
    print("You are in room 2")

    # ADD CODE FOR ROOM 2 HERE
    
    print("Type h to go back to the hallway")
    choice = input("Enter your choice")
    if choice.lower() == "h":
        hall()
    else:
        room2()

#-------------------- Main Program ----------------------
# This runs the functions
print("Welcome to the haunted mansion")
print("You have just walked through the main entrance")

hall()
