1. Introduction to Python Programming Part 1: Data Types, Print Function and Calculations

2. How to use this resource Within each unit, you will learn how to develop and apply a range of Python programming skills. Skill explanations are in pink . After reading the explanation of a skill, apply it within the given tasks. The tasks are categorised into Rookie (Easy), Pro (Medium) or Beast (Hard). Once you have learned how to apply your new skills, demonstrate your ability by completing the given challenges. Don’t forget the debugging task! Once complete, review your performance! Skill Explanations: Pink Slides Tasks: Rookie Pro Beast Challenges: Rookie Pro Beast

3. Learning Objectives Rookie To open and save a python program. To write simple print statements. To understand how to print different data types. Pro To combine string and integers within a single print statement. Beast To apply and combine python functions to improve programming efficiency.

4. Skill Contents Contents Confidence Level Data types (String & Integers) Print function Mathematical operations + - / * Using the comma , Using the newline character \n Once you complete a skill, colour code the box to show your level of confidence. You can always revisit the skill later on to boost your confidence. Key Colour Code I am very good at this skill and could show a friend how to do it. I am confident I can perform this skill on my own. I need to improve my understanding of this skill.

5. Data Types In programming, there are several different data types which can be used in different ways. Within these initial introduction tasks, the two main data types you will use are string and integers . String Integer Explanation Is a data type which represents text. Is a data type used to represent whole numbers. Example “Hello human, what is your name?” 11, 22, 555, 234, 7654321 Note : String is always written in “quotation marks”.

6. Task 1: Understanding String and Integers Within the table below, state if the data shown is a string or an integer : Data Data Type (String or Integer) “I love coding!” 1000000 “1966” “London hosted the 2012 Olympics”

7. Python Functions A Function is a section of code that performs a specific task. Python has many inbuilt functions which you will begin to learn about as you progress through these introduction activities. As a right of passage, the first piece of code all new programmers need to write the famous computer science phrase “ Hello World ” Within Python, to output a statement you need to use the print function.

8. Understanding the Python Tasks In order to learn some of the key python functions and programming techniques, you will complete a series of programming tasks split into the levels: Rookie (easiest), Pro (medium) and Beast (hardest). Afterwards, to assess your programming skills, you will complete a series of python challenges to measure your ability: Rookie, Pro or Beast. To help develop your understanding of programming, the solution for each task is presented in both flowchart and pseudo code.

9. print string: print integers: Notes: String is written within quotation marks. Integers don’t use quotation marks. Skill 1: Using the Print Function The python print function allows you to output information. Y ou write it like this: Type the information you want to output within the brackets (parenthesis).

10. Task 2: Rookie Flowchart Pseudo code Python START OUTPUT: Hello World END Output the famous programming phrase “ Hello World ”

11. Task 2: Solution

12. Addition + Subtraction - Division / Multiplication * Notes: We will investigate more uses for these symbols later on within the skills development. Skill 2: Mathematical Operations Python allows you to conduct calculations. The following symbols are used to conduct mathematical operations:

13. Task 3: Rookie Flowchart Pseudo code Python START OUTPUT: 365*12 END Output the answer to the following sum: 365*12

14. Task 3: Solution

15. Task 4: Rookie Flowchart Pseudo code Python START OUTPUT: The answer to the sum 123 x 456 is: OUTPUT: 123 * 456 END Write the following string statement and integer calculation: “ The answer to the sum 123 x 456 is: ” 123 * 456

16. Task 4: Solution

17. Task 5: Rookie Flowchart Pseudo code Python START OUTPUT: Hello World x 10 END Python also allows you to use some mathematical operators with string statements. Make the statement “ Hello World ” repeat 10 times .

18. Task 5: Solution

19. Code: Output: Notes: Using a comma allows you to output integers as part of a string sentence. Skill 3: Using the Comma The comma is used to separate character sets, e.g. string and integers . Using a comma also creates an automatic space.

20. Task 6: Pro Flowchart Pseudo code Python START OUTPUT: The answer to the sum 123 x 456 is: (123 x 456) END Output the following using an integer calculation and a comma , on the same line : The answer to the sum 123 x 456 is: 56088

21. Task 6 : Solution

22. Task 7: Pro Flowchart Pseudo code Python START OUTPUT: I only have [100-age] years to go until I reach 100! END Write the following using an integer calculation and a comma : I only have [100-age] years to go until I reach 100 !

23. Task 7: Solution

24. Code: Output: Notes: As you can see, Python identifies the newline character ( \n ) and splits the print output accordingly. Skill 4: Using the \n function The newline character is used to split output statements onto separate lines. You add it within string quotation marks.

25. Task 8: Beast Flowchart Pseudo code Python START OUTPUT: Hello World END Task : Write the following using the newline character \n : “ Hello World ”

26. Task 8 : Solution

27. Task 9: Beast Flowchart Pseudo code Python START OUTPUT: Hello World Hello World Hello World Hello World Hello World END Task : Make the statement “ Hello World ” repeat 5 times , on separate lines.

28. Task 9: Solution

29. Programming Challenges Now you have learned some programming skills, it’s time to put them into practice! Complete the following programming challenges. Start with the Rookie challenge and see how far you can push yourself. Finally, complete the debugging challenge . Once you have finished your challenges, complete the review . Look back at the skills you have learned so far to help you solve the challenge.
