Activity 1 - READ

A re-cap of terminology:

• variable declaration - storing data that will change whilst the code is running. The convention for this is to start with a lower case letter with the second, third or fourth words capitalised at the initial. e.g. myNewVariable
• constant declaration - storing data that won't change whilst the code is running. The convention for this is all upper case. e.g. MYCONSTANT
• initialisation - putting a value into a variable for the first time
• assignment - putting a value into a variable
• iteration - loop or repeat
• subroutine - store some code for me to use later on, as many times as I need
• function - a subroutine that returns a value
• procedure - a subroutine that doesn't return a value

Activity 2

Hashtag it out!

Copy and paste the code below into Python and use #hashtags to show where each of the keywords above are in the code. Two have been completed for you.

def multiply(x):

    return (x*5)

def chosen(option):

    if option == 1:

        GAME = "A list of numbers"

        print (GAME)

        for x in range(0,10):

            print (x)

        print (multiply(x))

        menu()

    else:

        quit()

def menu():

    print ("This is the menu")

    print ("----------------")

    print ("Choose from:")

    print ("1. Play")

    print ("2. Quit")

    option = int(input()) # variable declaration and initialisation

    while option not in [1,2]:

        print ("You must type 1 or 2")

        option = input() # variable assignment

    chosen(option)

menu()    

1. Find three applications that you have already made in Python.
2. Make sure that they work.
3. Open a new Python file.
4. Create a menu system.
5. Copy and paste the code for each of the three applications into the new Python file.
6. Use the menu system to allow a user to choose which application they would like to run.

Basically...put three of your applications into one file and make them accessible via a menu system

When you teach, make sure that you use the correct terminology for the aspects of programming. This will help to "drip feed" the correct words to the students.
