Decomposition And Abstraction
Akopọ
No programmer sits down and writes a large system in one single, unbroken sweep. Every real program, from a school attendance register to a banking app, starts life as a big, messy problem that has to be pulled apart before it can be solved. Two skills make that possible: decomposition, splitting a problem into manageable sub-problems, and abstraction, deciding which details actually matter for solving it.
This lesson works through how to analyse a problem properly before writing any code, how to break it down into sub-problems you can design and test independently, and how to turn a real-world idea, a book, a bank account, a bus timetable, into a simplified abstraction that Python can actually work with.
Awọn Afojusun
- Be able to analyse a problem, investigate requirements (inputs, outputs, processing, initialisation) and design solutions
- Be able to decompose a problem into smaller sub-problems
- Understand how abstraction can be used effectively to model aspects of the real world
- Be able to program abstractions of real-world examples

- What is decomposition? A) Removing irrelevant detail from a problem B) Splitting a problem into smaller sub-problems C) Testing a program with boundary data D) Converting pseudocode into program code Answer: B
- Which of these is an example of abstraction? A) Writing every possible detail about a real object into a program B) Representing a book using only title, author and availability C) Splitting a program into functions D) Testing a function with erroneous data Answer: B
- In problem analysis, what does 'initialisation' mean? A) The final output of the program B) Giving a variable a starting value before processing begins C) The list of inputs a program requires D) Removing an unused variable Answer: B
- A sub-problem is still too complex to design as a single function. What should happen next? A) The whole program should be abandoned B) The sub-problem should be decomposed further C) All detail about it should be abstracted away D) It should be left as one long function regardless Answer: B
- Why is functional (procedural) abstraction useful? A) It lets other code use a function without knowing how it works internally B) It removes the need for a function to have parameters C) It guarantees a program has no errors D) It automatically decomposes a problem Answer: A
