4. IDLE Function Program Code
The Python IDLE
Load It up – you should see a screen like the one shown – this is the Python Shell
IDLE stands for “Integrated Development Environment” – it is the place where a set of tools have been created that allow us to code.

8. IDLE Function Program Code
Python Files
When you create a program directly in the Python shell it can be only be used once.
You should always create separate Python files that can be saved for use later.

9. IDLE Function Program Code
Adding Comments
To make your program easier to understand you may wish to add comments to a program - this is easy, you simply use the # key
print(“Game Over”)
# prints onto screen
You will notice that your comments are displayed in red – this is another example of Syntax highlighting

Task 3
Main Name program
Create a program by open a new Python file.
Print out your full name
Print out your favourite colour
Include a comment
Save it in your Python Programming folder as 1.Full name

11. Understanding Variables
A variable is a way of labelling and accessing information from a stored location.
In the example ‘name’ is the variable. ‘Larry’ is a string that has been assigned to the variable.
Changing Larry changes the variable but ‘name’ remains the same.
Learning Objectives

12. Getting User Input
If we create the variable as an Input there is a lot more we can do with it.
Copy the code shown into a new Python file. Save it as 1.personal greeter
Extension
Try to add more questions into your program to find out information about someone.
Learning Objectives

13. secondLine = "That tonight's gonna be a good, good night."
Extension work
Line Breaks / New Lines
You can also write your string over several lines by using “\n”. Like this:
firstLine = "I got a feeling,\nThat tonight's gonna be a good night.\n"
secondLine = "That tonight's gonna be a good, good night."
print(firstLine + secondLine)
Try writing a few of your own!

14. Lesson 2

15. IDLE Function Program Code
Starter task
On your post it note try to explain the what is meant by:
A variable
A String
Learning Objectives
To understand what an integer is.
To be able to create Python programs that make use of integers.
Key Words
IDLE Function Program Code

16. Open Python > IDLE (python GUI)
Exercise 1
 Try typing each of the following at the command prompt: (press Enter after each 1).
 2+2
17-9
16/4
3*7
Learning Objectives
To understand what an integer is.
To be able to create Python programs that make use of integers.

17. number1 = input("Please enter a number between 1 & 100 "))
Using integers
Copy the code below.
number1 = input("Please enter a number between 1 & 100 "))
number2 = input("Please enter a number between 1 & 100 "))
print ("number 1 + number 2 =",number1+number2)
Save your program as 2.Adding.
Can you spot what has gone wrong?
Learning Objectives
To understand what an integer is.
To be able to create Python programs that make use of integers.

18. number1 = int(input("Please enter a number between 1 & 100 "))
Using integers
Integers are essentially whole numbers.
Copy the code below.
number1 = int(input("Please enter a number between 1 & 100 "))
number2 = int(input("Please enter a number between 1 & 100 "))
print ("number 1 + number 2 =",number1+number2)
Now edit your program so that it treats the data as integers.
By putting int( at the front of the input command we are telling Python we want it treat the data as a whole number and not a String(text).
For each set of brackets you have opened you must close the same amount at the of the line.

19. Learning Objectives Using integers – Task Subtraction
Edit your code to make it subtract the two numbers. Save it as “2.subtraction” and test it works.
Multiplication
Edit your code to make it multiply the two numbers. Save it as “multiplication” and test it works
Division
Edit your code to make it divide the two numbers. Save it as “division” and test it works.
Mod
Edit your code to make it calculate the modulus (remainder) of a division. Save it as “mod.py” and test it works. (Hint: use x%y)
Square
Edit your code to make it calculate x2. Save it as “square” and test it works.
Learning Objectives

20. Learning Objectives Using integers – Task 2
Order of Operations / BIDMAS
· Brackets
· Indices (powers)
· Division and Multiplication. Start on the left and work them out in the order that you find them.
· Addition and Subtraction. When only addition and subtraction are left in the sum work them out in the order you find them. starting from the left of the sum and working towards the right
Try writing a program that will take a number, multiply by three and then add four.
Try writing a program that will take a number, add four and then multiply by three.
Put the number 7 into both programs and check that they work correctly.

21. Lesson 3 Learning Objectives
To understand what a selection means in programming .
To be able to create Python programs that make use of IF statements.

22. IDLE Selection IF statement Code
Starter task
Spot the error in the code on your piece of paper.
There are 5 in total.
Learning Objectives
To understand what a selection means in programming .
To be able to create Python programs that make use of IF statements.
Key Words
IDLE Selection IF statement Code

23. IDLE Selection IF statement Code
Selection means selecting (or choosing) what to do next.
Should I cycle to school, or ask for a lift? If it’s a sunny day I might cycle. If it’s raining, I’ll ask for a lift.
Learning Objectives
To understand what a selection means in programming .
To be able to create Python programs that make use of IF statements.
Key Words
IDLE Selection IF statement Code

24. Learning Objectives IF ... ELSE
Create a new file and type in the following code, Save it as 3.IF:
hours = int(input(“How many hours a day do you play computer games? “))
if hours < 2:
print(“That seems a fairly healthy balance. Well done!”)
else:
print(“You’re probably good enough by now with all that practice.”)
There are a number of key points here:
Notice how the colon (:) is used to say what should happen in each case.
Also notice that the indentation is VERY important.
Python only knows when your IF statement is finished by looking at the indentation!
Learning Objectives
To understand what an integer is.
To be able to create Python programs that make use of integers.

25. IF ... ELIF ... ELSE
Sometimes there are more than two options: I could walk OR cycle OR get the bus OR get a lift. As well as IF and ELSE, we can stick an ‘ELSE IF’ (or ELIF) in the middle:
Create a new file and type in the following code, save it 3.ELIF:
hours = int(input(“How many hours a day do you play computer games? “))
if hours < 2:
print(“That seems a fairly healthy balance. Well done!”)
elif hours < 4:
print(“You’re probably good enough by now with all that practice.”)
else:
print(“Put the controller down and get some fresh air once in a while!”)
Learning Objectives
To understand what an integer is.
To be able to create Python programs that make use of integers.

26. There are a couple of important bits here:
IF ... ELIF ... ELIF ... ELIF ... ELSE
You can include an unlimited number of ELIFs if you need to. Try the following:
menu = "What would you like a quote about:\n\
1. Ability\n\
2. Boredom\n\
3. Cats?\n\
9. Quit\n“
choice = int(input(menu))
if choice == 1:
print("Great ability develops and reveals itself increasingly with every new assignment.\n Baltasar”)
elif choice == 2:
print("The secret of being boring is to say everything.\n Voltaire")
elif choice == 3:
print("Cats regard people as warmblooded furniture.\n Jacquelyn Mitchard")
elif choice == 9:
print("Goodbye!!!")
There are a couple of important bits here:
You can put a line break in your string by using “\n”.
You can continue a line of code by putting a “\” at the end.
If you are testing for equality, use a double equals (is 3x2 = = 6?)
Make your own program that uses a menu system and give the user a response
