Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils discover how iteration is used to replicate parts of a program. They will analyse the difference between count and condition controlled iteration and how trace tables can be used to trace through loops. They will explore data validation techniques and robust program design.
Lesson Summary
You will learn to import the random module into your code to produce random numbers.
Key Notes
- Be able to locate information using the language documentation.
- Import modules into your code.
- Demonstrate how to generate random numbers.
Vocabulary To Learn
- module: a file with pre-made code you can use in your own programs
- standard library: a collection of built-in modules that come with Python
Common Mistakes To Avoid
- You have to write the full code for random number generation yourself.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Be able to locate information using the language documentation. Import modules into your code.
2. Define this computing term and give one practical example. 'module'
a file with pre-made code you can use in your own programs. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: You have to write the full code for random number generation yourself. Correction: Python's standard library includes the random module, which already has functions like randint() to generate random numbers. You just need to import it.
