Python Coding challenge - Day 854| What is the output of the following Python Code?

Code Explanation:

1. Class Definition

class Person:

This defines a new class named Person.

A class is a blueprint for creating objects.

Each object of this class can have its own attributes like name, age, etc.

2. Constructor Method

    def __init__(self, name):

        self.name = name

__init__ is the constructor method in Python.

It runs automatically when a new object of Person is created.

name is a parameter passed during object creation.

self.name = name assigns the value of name to the object’s attribute name.

3. Creating an Object

p = Person("Alice")

This creates an object p of class Person.

The constructor is called with name = "Alice".

The object now has an attribute p.name = "Alice".

4. Adding a Dynamic Attribute

p.age = 25

Here, a new attribute age is added dynamically to the object p.

Python allows adding attributes outside the constructor.

Now, p has two attributes: name = "Alice" and age = 25.

5. Accessing the Dynamic Attribute

print(p.age)

Accessing p.age retrieves the dynamically added attribute.

Python prints the value of age, which is:

Final Output:

25

Python Coding challenge - Day 853| What is the output of the following Python Code?

Code Explanation:

1. Class Definition

class Circle:

This defines a new class named Circle.

A class is a blueprint for creating objects.

Circle objects will represent circles with a radius.

2. Constructor Method

    def __init__(self, r):

        self._radius = r

__init__ is the constructor method in Python. It runs automatically when a new object is created.

r is a parameter passed during object creation.

self._radius = r stores the radius value in a protected attribute _radius.

By convention, attributes with a single underscore _ are protected, meaning they should not be accessed directly from outside, but are still technically accessible.

3. Property Decorator

    @property

    def radius(self):

        return self._radius

@property makes the radius() method behave like a read-only attribute.

When you access c.radius, Python calls this method automatically.

return self._radius returns the value of the protected attribute _radius.

Benefit: You can later add validation or calculations without changing how you access the attribute.

4. Creating an Object

c = Circle(5)

This creates an object c of the class Circle.

The constructor __init__ is called with r=5.

The object now has _radius = 5.

5. Accessing the Property

print(c.radius)

Accessing c.radius calls the radius property method.

The method returns the value of _radius, which is 5.

Python prints 5.

Final Output

5

Python Coding Challenge - Question with Answer (01171125)

 

Explanation:

Assign a value to num

num = 5

We set num = 5.

We will use this value for checking divisibility.

Create the list a

a = [5, 10, 11, 13]

This list contains four numbers:

5, 10, 11, 13

Initialize sum variable

s = 0

We create s to store the total of selected numbers.

Starting value = 0

Start loop — go through each value in list

for v in a:

The loop takes each value v from the list:

First: v = 5

Then: v = 10

Then: v = 11

Then: v = 13

Check divisibility using IF + continue

    if v % num == 0:

        continue

We check:

If v is divisible by num (5), skip it.

Check each:

v v % 5 Divisible? Action

5 0             Yes         Skip

10 0             Yes         Skip

11 1              No         Add

13 3              No         Add

continue means: skip the rest of the loop and go to the next number.

Add the non-skipped values

    s += v

Only numbers NOT divisible by 5 get added:

s = 11 + 13 = 24

Print the final answer

print(s)

So the output is:

24

Python Coding challenge - Day 852| What is the output of the following Python Code?

 

Code Explanation:

1. Defining Class A

class A:

You begin by creating a class named A.

This class contains a method that performs a simple calculation.

2. Defining the calc() Method in A

    def calc(self, x):

        return x + 1

A method named calc() is defined.

It takes two arguments:

self → refers to the object

x → the input number

The method returns x + 1.

Example: If x = 3 → returns 4.

3. Defining Class B That Inherits A

class B(A):

Class B is created.

It inherits from class A.

This means B automatically gets A’s calc() method, unless overridden.

4. Overriding calc() Inside Class B

    def calc(self, x):

        return super().calc(x) * 2

B provides its own version of calc(), overriding A’s version.

super().calc(x) calls the parent class A’s calc() method.

A’s calc() returns x + 1.

B then multiplies that result by 2.

So the logic becomes:

(super result) * 2= (x + 1) * 2

5. Creating an Object of Class B

obj = B()

An object of class B is created.

It uses B’s calc() method (overridden version).

6. Calling calc() With Argument 3

print(obj.calc(3))

Step-by-step evaluation:

B’s calc(3) is called

super().calc(3) → calls A’s calc(3) → returns 4

B multiplies result: 4 × 2 = 8

Print output: 8

Final Output: 8

Python Coding challenge - Day 851| What is the output of the following Python Code?

 

Code Explanation:

1. Defining Class R

class R:

You begin by creating a class named R, which will have an initializer and a private attribute.

2. Constructor of Class R

    def __init__(self):

        self.__v = 10

__init__ runs automatically when an object of R (or its child class) is created.

self.__v is a private attribute because it starts with double underscore __.

Python performs name-mangling, converting __v into _R__v internally.

This means subclasses cannot directly access __v using the name __v.

3. Defining Class S that Inherits R

class S(R):

Class S is a child class of R.

It inherits the constructor of class R, so __v is still created inside objects of class S (but as _R__v).

4. Method show() Inside Class S

    def show(self):

        return hasattr(self, "__v")

The method checks: Does the object have an attribute named "__v"?

Because of name-mangling, the actual attribute name is _R__v, not __v.

So hasattr(self, "__v") will return False.

5. Creating an Object of S and Calling show()

print(S().show())

An object of S is created → this also runs R’s constructor → _R__v is created.

Now show() is called.

hasattr(self, "__v") checks for "__v" exactly.

Since "__v" does not exist (only _R__v does), the result is:

False

Final Output: False
