Variables can store
• Text
• Numbers
• Decimals
• True or false

#### Slide 3 -Tekstslide

Recall Quiz
Try these questions on things we have covered over the past few lessons.

#### Slide 4 -Tekstslide

B
Selection
C

D
Recursion

#### Slide 5 -Quizvraag

Code that repeats/loops is known as coding in...
A
Sequence
B
Selection
C
Iteration
D
Recursion

#### Slide 6 -Quizvraag

Code that only runs when a condition is met is known as coding in...
A
Sequence
B
Selection
C
Iteration
D

#### Slide 7 -Quizvraag

An example of a loop in python would be:
A
print("this")
B
while x > 0 :
C
if x == 0 :
D
name = input("-->")

#### Slide 8 -Quizvraag

A value that is used by the program and can change is known as a...
A
Loop
B
If statement
C
function
D

A
!=
B
==
C
=
D
"="

#### Slide 10 -Quizvraag

#### Slide 11 -Open vraag

Refresh
Time to refresh those skills

#### Slide 12 -Tekstslide

Outputs
Used to output messages to the screen
In Python we use print
print ("hello world")

#### Slide 13 -Tekstslide

Variables
An area in memory used to store a value the program will use.
The value is likely to change
Here are some examples in Python
name = "Dave"                      - Text
health = 100                           - Integer
Player_dead = False                  - Boolean  (True/False)

#### Slide 15 -Tekstslide

Inputs
We often use variables to store inputs from the user
In Python we use input
input ("Question the user will see as a prompt")
So to store a name we would use:
name = input ("What is your name  ? -->  ")

#### Slide 16 -Tekstslide

filmpref = input("What kind of films do you like? ")

Label the correct parts of the code with the symbols.
This the the variable name given to a piece of information
This will allow the user to enter information that will be saved to the variable.
This is a string, we place a question inside so the user knows which information to enter.

#### Slide 17 -Sleepvraag

CORRECT
CAUSE AN ERROR
print = ("Hello")
Print("Yes!")
print("this one)
name = imput("what is your name")
name = input("what is your name")
print("this text")
fav colour = "Green"
age = 10
print("Hello", name)
print("Bye",name")

#### Slide 19 -Sleepvraag

IF/ELIF/ELSE
When we need to make a decision in a program we use a selection statement.
In Python we use if  elif  and  else

Let's look at some coded examples...

Now Try Yourself

#### Slide 24 -Quizvraag
