Quick explanation
Random number generation in a programming language: Be familiar with, and be able to use, random number generation
- This point belongs to Programming, especially Random number generation in a programming language.
- You need to be able to random number generation in a programming language: Be familiar with, and be able to use, random number generation.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Why it matters
This objective helps connect Random number generation in a programming language to exam-style questions, flashcards, and revision notes for Programming.
Quick student answer
Which Python statement generates a random integer from 1 to 6 inclusive?
Direct answer
random.randint(1, 6)
Key terms
- Random number generation: Using a programming language feature or function to produce a value selected within a specified range.
- Inclusive range: A range in which both the lower limit and upper limit can be generated.
Common trap
Excluding the upper limit: Remember that Python randint includes both limits, so use random.randint(1, 6) for the range 1 to 6 inclusive.

- Data types: Understand the concept of a data type. Understand and use the following appropriately: • integer • real/float • Boolean • character • string • date/time • pointer/reference • records (or equivalent) • arrays (or equivalent). Variables declared as a pointer or reference data type are used as stores for memory addresses of objects created at runtime, ie dynamically. Not all languages support explicit pointer types, but students should have an opportunity to understand this data type. Define and use user-defined data types based on language-defined (built-in) data types.
Data types
- Programming concepts: Use, understand and know how the following statement types can be combined in programs: • variable declaration • constant declaration • assignment • iteration • selection • subroutine (procedure/function). The three combining principles (sequence, iteration/repetition and selection/choice) are basic to all imperative programming languages. Use definite and indefinite iteration, including indefinite iteration with the condition(s) at the start or the end of the iterative structure. A theoretical understanding of condition(s) at either end of an iterative structure is required, regardless of whether they are supported by the language being used. Use nested selection and nested iteration structures. Use meaningful identifier names and know why it is important to use them.
