Unit Summary
This unit introduces pupils to text-based programming with Python. Pupils start with programs involving input and output, and gradually move on to using arithmetic operations, randomness, selection, and iteration. Pupils will consolidate these skills in a project at the end of the unit.
Lesson Summary
You will learn to create a text-based program from an algorithm that includes input and output.
Key Notes
- An algorithm is a sequence of steps that can be followed to do a task.
- A program is a set of commands that can be run by a computer in order for it to do a task.
- All programming languages have rules for syntax that must be followed so that the program can run.
- The print() function is used to output information from a Python program.
- The input() function is used to input data from the user into a Python program.
Vocabulary To Learn
- algorithm: a set of step-by-step instructions to solve a problem
- program: a set of commands that can be run by a computer in order for it to do a task
- syntax: the precise way that a program must be written to be understood by a computer
Common Mistakes To Avoid
- Pupils will modify their code to provide input directly in to the input() function, for example, user = input("Aisha"), rather than typing when asked as the program runs.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
An algorithm is a sequence of steps that can be followed to do a task. A program is a set of commands that can be run by a computer in order for it to do a task.
2. Define this computing term and give one practical example. 'algorithm'
a set of step-by-step instructions to solve a problem. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: Pupils will modify their code to provide input directly in to the input() function, for example, user = input("Aisha"), rather than typing when asked as the program runs. Correction: The computer follows the instructions of a program. Input that a user has to type in should only be entered when the program runs. This allows different users to provide different inputs without changing the program in any way.
