Python OOPS Challenge | Day 14 | What is the output of following Python code?

This code snippet demonstrates method overriding in object-oriented programming.

Explanation:

1. Class MemoryDevice:

It has a method printPhysicalSize that prints "medium".

2. Class SDCard:

It inherits from MemoryDevice.

It overrides the printPhysicalSize method to print "small" instead.

3. Code Execution:

sdCard = SDCard() creates an instance of the SDCard class.

sdCard.printPhysicalSize() calls the printPhysicalSize method of the SDCard class (because it overrides the method in the parent class).

Key Concept:

When a method in a subclass overrides a method in the parent class, the subclass version is executed for objects of the subclass.

Output:

The method in SDCard prints "small". Therefore, the correct answer is: small.

Python OOPS Challenge | Day 13 | What is the output of following Python code?

In this code snippet, there are two classes, Device and Tablet. Here's a breakdown of what happens:

1. Class Device:

The Device class has a method printSize that, when called, prints the string "medium".

2. Class Tablet:

The Tablet class inherits from Device but does not define any additional methods or attributes. Therefore, it inherits all methods from Device, including printSize.

3. Creating an Instance of Tablet:

tablet = Tablet() creates an instance of the Tablet class.

4. Calling printSize Method:

tablet.printSize() calls the printSize method on the Tablet instance. Since Tablet inherits Device and does not override printSize, it uses the printSize method from Device, which prints "medium".

Output: The correct answer is "medium".

Python OOPS Challenge | Day 12| What is the output of following Python code?

In this code snippet, one class is defined, which is named Tablet. The class definition begins with class Tablet: and includes a pass statement, which acts as a placeholder, meaning the class has no methods or attributes defined inside it for now.

After defining the class, two instances (or objects) of the Tablet class are created: tablet1 and tablet2. These are variables that hold instances of the Tablet class, not additional class definitions.

So, the answer is 1, as there is only one class (Tablet) defined in the code segment.

Python OOPS Challenge | Day 11 | What is the output of following Python code?

In this code snippet, the output will be an Exception. Here’s why:

1. The TV class is defined with no attributes or methods (pass is used as a placeholder).

2. An instance of the TV class, obj, is created.

3. A new attribute price is assigned to obj with the value 200. This attribute is dynamically added to the instance obj but is not part of the TV class itself.

4. The code then attempts to print self.price. However, self is not defined in the current scope. In Python, self is a conventionally used parameter name that refers to the instance of the class within a method of the class. Since this code tries to access self outside of a class method, it will raise a NameError for the undefined variable self.

To fix this and print the price, you would need to use obj.price instead:

print(obj.price)

This would correctly print 200.

Python OOPS Challenge | Day 10 | What is the output of following Python code?

This code snippet demonstrates runtime polymorphism. Here’s why:

1. Polymorphism allows a method in a subclass to have the same name as a method in its superclass but behave differently. In this example, the printWeight() method is defined in both the PolarAnimal superclass and the Penguin subclass.

2. Method Overriding: The Penguin subclass overrides the printWeight() method of PolarAnimal. This means that if an object of Penguin is used to call printWeight(), it will execute the print("heavy") line instead of print("light") defined in the superclass.

3. Runtime Polymorphism (also known as dynamic polymorphism) happens at runtime, where the method to execute is determined based on the actual object type (i.e., whether it’s a Penguin or PolarAnimal instance) rather than at compile time.

Since printWeight() behaves differently in Penguin than in PolarAnimal, it demonstrates runtime polymorphism.

Python OOPS Challenge | Day 9 | What is the output of following Python code?

In this code snippet, we have two classes: OSDevice and SmartTV. The SmartTV class inherits from the OSDevice class.

Code Analysis

1. The OSDevice class has a method called printSize, which prints "medium".

2. The SmartTV class has its own printSize method that overrides the one from OSDevice and prints "large".

When we create an instance of SmartTV with obj = SmartTV() and call obj.printSize(), Python will look for the printSize method in the SmartTV class first. Since SmartTV has its own printSize method, it overrides the printSize method in OSDevice. Therefore, only "large" is printed.

Output

The output of this code will be:

large

So, the correct answer is the second option: large.

Python OOPS Challenge | Day 8 |What is the output of following Python code?

In this code snippet, we have two classes: Fruit and Apple. The Apple class inherits from the Fruit class.

Code Analysis

1. The Fruit class has an __init__ method (constructor) that prints '1'.

2. The Apple class also has its own __init__ method that overrides the one from Fruit and prints '2'.

When we create an instance of Apple with obj = Apple(), Python will look for the __init__ method in the Apple class first. Since Apple has its own __init__ method, it overrides the __init__ method of Fruit. Therefore, only '2' is printed.

Output

The output of this code will be:

2

So, the correct answer is the second option: 2.

Python OOPS Challenge | Day 7 |What is the output of following Python code?

Let's go through this code snippet step-by-step:

try:

    print("1")

    raise Exception("2")

    print("3")

except Exception as e:

    print(str(e))

    print("4")

Explanation:

1. try Block Execution:

print("1"): This line executes first and outputs 1.

raise Exception("2"): This line raises an exception with the message "2". Because an exception is raised, the code execution immediately jumps to the except block, and the line print("3") is never executed.

2. except Block Execution:

print(str(e)): This line executes next, printing the exception message "2".

print("4"): This line then executes, printing 4.

Final Output:

The output is:

1

2

4

Correct Answer:

The correct answer is 124.

Python OOPS Challenge | Day 6 |What is the output of following Python code?

In this code, we define a class Rectangle with an initializer method __init__ and a method calcPerimeter to calculate the perimeter of the rectangle.

Code Breakdown:

1. __init__ method: This is the constructor of the class. When an object of the Rectangle class is created, it initializes the attributes a and b with the values provided as arguments.

def __init__(self, aVal, bVal):

    self.a = aVal

    self.b = bVal

Here, self.a and self.b are set to aVal and bVal, respectively.

2. calcPerimeter method: This method calculates the perimeter of the rectangle using the formula .

def calcPerimeter(self):

    return 2 * self.a + 2 * self.b

3. Creating an object and calling calcPerimeter:

obj = Rectangle(1, 5)

print(obj.calcPerimeter())

Here, we create an object obj of the Rectangle class with a = 1 and b = 5.

Then, calcPerimeter is called on obj, which calculates .

Output:

The output of this code is 12.

Python OOPS Challenge! Day 4 | What is the output of following Python code?

In this code snippet, an attempt is made to create an instance of the class SpaceObject, which inherits from ABC (Abstract Base Class) from Python's abc module. Here’s the breakdown of the code:

Explanation

1. Abstract Base Class (ABC):

The class SpaceObject inherits from ABC, which is used to define abstract base classes.

However, SpaceObject does not contain any abstract methods (methods decorated with @abstractmethod), making it a concrete class, even though it inherits from ABC.

2. Object Creation:

Since there are no abstract methods in SpaceObject, it is possible to instantiate this class directly.

The code obj = SpaceObject() will execute without any issues.

3. Output:

After creating the object, print('Object Creation') is called, which will print Object Creation to the console.

Conclusion

The correct answer is:

Object Creation

Python OOPS Challenge! Day 5 | What is the output of following Python code?

The code snippet contains a class Tablet with a static method printModel. However, there’s an issue with how this static method is defined and used.

Explanation

1. Static Method Misuse:

printModel is decorated with @staticmethod, which means it should not accept any arguments except for optional ones. However, self is being used as a parameter, which is misleading.

Static methods do not have access to instance-specific data, so they cannot use self to access instance attributes like self.model.

2. Error Triggered:

When Tablet.printModel() is called, it tries to execute print(self.model).

Because printModel is a static method, self is not automatically passed, leading to a missing argument error.

This will raise a TypeError, saying something like "printModel() takes 0 positional arguments but 1 was given."

Output

The correct answer is:

Exception
