Python
On the road to code!

Slide 1 - Tekstslide

What is Python Programming?

Slide 2 - Woordweb

Python
  • High level programming language
  • Allows you to create your own programs
  • Text based

Slide 3 - Tekstslide

KO - Learn to program with Python
  • All - Use the print function to output some text on the screen
  • Most - Create a variable that stores text data that can then be displayed on the screen in a story
  • Some - Can explain the link between machine code and high level language

Slide 4 - Tekstslide

Recall
Try these old recall questions on things you should know about programming

Slide 5 - Tekstslide

Code that runs one line after another is known as coding in...
A
Sequence
B
Selection
C
Iteration
D
Recursion

Slide 6 - Quizvraag

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

Slide 7 - Quizvraag

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

Slide 8 - 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 9 - Quizvraag

A value that is used by the program and can change is known as a...
A
constant
B
procedure
C
function
D
variable

Slide 10 - Quizvraag

Refresh
Time to refresh those skills

Slide 11 - Tekstslide

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

Slide 12 - Tekstslide

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
discount = False                  - Boolean  (True/False)

Slide 14 - 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 15 - Tekstslide

KO - Learn to program with Python
  • All - Use the print function to output some text on the screen
  • Most - Create a variable that stores text data that can then be displayed on the screen in a story
  • Some - Can explain the link between machine code and high level language

Slide 16 - Tekstslide

Label the correct parts of this code (drag them - text at the bottom).
filmpref = input("What kind of films do you like? ")
Checkpoint
Variable
Function
Parameters

Slide 17 - Sleepvraag

Slide 18 - Tekstslide

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")

Here are some examples in Python
name = "Dave"                      - Text 
health = 100                           - Integer
discount = False                  - Boolean  (True/False)

Slide 24 - Tekstslide

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 29 - Tekstslide

In python you must write IF, ELIF and ELSE in capital letters
A
TRUE
B
FALSE

Slide 31 - Quizvraag

After every if, elif and else statement you put ...
A
;
B
}
C
:
D
#

Slide 32 - Quizvraag

An elif part of the code will only run if the if part was not met
A
True
B
False

Slide 33 - Quizvraag

an if statement must always have an else component
A
True
B
False

Slide 34 - Quizvraag

which of the following if statements would cause an error

While Loops
Sometimes you need the computer to repeat steps until a certain condition has been met
In Python we use while  and  for

Let's look at some coded examples of a while loop...
