1. programming in python
Lesson 2

2. Starter Activity
Complete the starter activity

3. Recap Starter Recap starter What is wrong with it? print(“hello)
print(“hello)
number = 17
number 17
print(“Your number is”,number)
PRint(“bye”)
print(“hello”)
print(“bye”)

4. Lesson Outcomes
All-Level 4- Know the key data types discussed in lesson
With help be able to write a variable with help
To be able to store a user inputted variable with help
Understand and demonstrate the basic data types
Most-Level 5- Be able to write a these with little help.
Some-Level 6- independently write these and adapt them

5. Recap Lets recap what we learnt last lesson What is a program?
A program is a sequence of instructions that specifies how to perform a computation.
What is syntax?
Refers to the spelling and grammar of a programming language
Recap starter. Possible opportunity for grading/formative/summative assessment through the sheets.

6. Variables
One of the most powerful features of a programming language is the ability to manipulate variables.
A variable is a name that refers to a value.
The assignment statement creates new variables and gives them values:
>>> message = "What's up, Doc?“
>>> n = 17
Demonstrate on board

7. Variables >>> N = 17 >>> N >>> 17
Assignment/Input
>>> N = 17 >>> N >>> 17
Variable
Result/Output
Demonstrate this with an example in Python

8. Task 1 Variables If you are stuck you can download the Help program
Using variables to demonstrate basic math code. + - / *
E.g.
Number 1 + number 1
Variables
If you are stuck you can download the Help program

9. Task 2 Have a look at this line of code print(“Your number is”,number)
number is a variable
The comma separates the text and the variable
Your task is to write a code that prints a name and displays it. Have a look at the starter task to help you.

10. input
Now we know what a variable is we can use the input statement to store things.
>>> print(“what is your name”)
>>>name = input()
>>>print(name)
Copy this on the board
Adapt this code to something of your choosing e.g. a user inputs their details then you display them

11. Data types Integer Float String Boolean
There are mean other numbers but we will stick to these main ones

12. Data Types
Examples of strings are: 'Hello', "Goodbye". To input a string, use input()
Examples of integers are: 2, 6, -89, To input an integer at the screen, use int(input())
Examples of floats are: 2.4, 6.0, , To input a float number at the screen, use float(input())
A boolean variable always has the value True or False. Remember Python is case sensitive so the capital 'T' and 'F' really matters!

13. Data types What is a string?
Examples of strings are: 'Hello', "Goodbye".
How do you enter it?
Input()
What is a integer
are: 2, 6, -89,
int(input())
What is a float number
float(input())
What is a boolean?
has the value True or False.
Variableboolean = True

14. Task 4 Have a go at entering these values and displaying them
strings are: 'Hello', "Goodbye". To input a string, use input()
integers are: 2, 6, -89, To input an integer at the screen, use int(input())
2.4, 6.0, , To input a float number at the screen, use float(input())
A boolean variable always has the value True or False. Remember Python is case sensitive so the capital 'T' and 'F' really matters!

15. Task 3
Your code should look something like this

16. Self Evaluation Task Open the Self Evaluation Task.
Have a look at the outcomes of the lesson.
Write down the level you think you got this lesson
Self evaluate your progress this lesson and write your Level and your Student Next Step.

17. Plenary
Now we know what a variable is we can use the input statement to store things.
>>> print(“what is your name”)
>>>name = _________
>>>print(name)
input()

18. Plenary Integer _______ String
There are mean other numbers but we will stick to these main ones
Float
Boolean

19. Plenary 'Hello', "Goodbye". 2, 6, -89, 45421. float(input())
What is a string?
Examples of strings are:
How do you enter it?
Input()
What is a integer
are:
int(input())
What is a float number
What is a boolean?
has the value True or False.
Variableboolean = True
'Hello', "Goodbye".
2, 6, -89,
float(input())
