The correct answer is that the super() function can be used to call a method from a parent class, because super() provides a way to access inherited methods in a child class, especially when dealing with multiple base classes in Python class inheritance. This function resolves the method resolution order (MRO) automatically, ensuring that each parent class’s method is called exactly once, which is critical for avoiding duplication in diamond inheritance patterns. On the Certified Associate Python Programmer PCAP exam, this concept tests your understanding of how Python handles multiple inheritance and the cooperative use of super() to maintain clean, predictable behavior. A common trap is assuming super() only works with single inheritance or that it simply calls the immediate parent, when in fact it follows the MRO chain. Memory tip: think of super() as the “next in line” delegate, not just the direct parent.
PCAP Object-Oriented Programming Practice Question
This PCAP practice question tests your understanding of object-oriented programming. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE statements about inheritance in Python are correct?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A child class inherits all attributes and methods from its parent class.
Option A is correct because in Python, a child class inherits all non-private attributes and methods from its parent class by default. This includes both data attributes and methods, allowing the child to reuse and extend the parent's behavior without redefinition. Private attributes (with double underscore prefix) are name-mangled to _Classname__attribute, but they are still inherited in the sense that they exist in the child's namespace under the mangled name, though direct access by the original name is restricted.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
A child class inherits all attributes and methods from its parent class.
Why this is correct
Correct, except for name-mangled ones.

Read the scenario before looking for a memorised answer.
✗
Private attributes (with __) are inherited unchanged.
Why it's wrong here
Name mangling renames them, so they are not directly inherited.
✓
Python supports multiple inheritance.
Why this is correct
Correct.

✗
Python supports method overloading based on parameters.
Why it's wrong here
Python does not support method overloading; methods override.
✓
The super() function can be used to call a method from a parent class.
Why this is correct
Correct.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Python Institute often tests the misconception that private attributes (__name) are completely hidden or not inherited, when in fact they are inherited but name-mangled, and that Python supports method overloading like Java or C++, when it actually relies on default arguments and single method definitions.
Detailed technical explanation
How to think about this question
Under the hood, Python's inheritance uses the MRO (Method Resolution Order) via the C3 linearization algorithm to determine which method to call when a method is invoked on an instance. The super() function leverages this MRO to call the next method in the chain, which is crucial for cooperative multiple inheritance (e.g., in diamond inheritance scenarios). In real-world frameworks like Django, super() is commonly used in model inheritance to ensure proper initialization of parent classes.

Key takeaway

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which TWO of the following statements about Python class inheritance are correct? (Select exactly two.)
easy
A.If a subclass does not define __init__, it automatically inherits the parent's __init__.
✓ B.A subclass can override a parent class method.
C.A subclass cannot define methods with the same name as a parent class method.
D.A subclass inherits all private attributes and methods from the parent class.
✓ E.A class can inherit from multiple base classes.
Why B: Option B is correct because Python allows a subclass to define a method with the same name as a method in its parent class, which overrides the parent's implementation. When the method is called on an instance of the subclass, Python's method resolution order (MRO) will find the subclass's version first, effectively hiding the parent's method.
Variation 2. Which of the following statements about class inheritance in Python are true? (Choose two.)
easy
A.A class can inherit from only one base class.
✓ B.Abstract base classes can be defined using the ABC module.
C.A child class can override any method from its parent class, but only if the method is declared as virtual.
D.The super() function is used to call a method from a sibling class.
✓ E.Python supports multiple inheritance.
Why B: Option B is correct because Python's `abc` module (Abstract Base Classes) allows you to define abstract base classes by inheriting from `ABC` and using the `@abstractmethod` decorator. This enforces that subclasses must implement the abstract methods, providing a formal interface contract.
