There are 4 modules in this course


This course is the second course in the specialization exploring both computational thinking and beginning C programming. Rather than trying to define computational thinking, we’ll just say it’s a problem-solving process that includes lots of different components. Most people have a better understanding of what beginning C programming means!

This course assumes you have the prerequisite knowledge from the previous course in the specialization. You should make sure you have that knowledge, either by taking that previous course or from personal experience, before tackling this course. The required prerequisite knowledge is listed below. 

Prerequisite computational thinking knowledge: Algorithms and procedures, data collection
Prerequisite C knowledge: Data types, variables, constants, and STEM computations

Throughout this course you'll learn about data analysis and data representation, which are computational thinking techniques that help us understand what sets of data have to tell us. For the programming topics, you'll continue building on your C knowledge by implementing selection, which lets us decide which code to execute, and iteration (or looping), which lets us repeat chunks of code multiple times.

Module 1: Learn about some common statistics we can calculate as we analyze sets of data
Module 2: Discover how we make decisions in our code
Module 3: Explore the various ways we can represent sets of data
Module 4: Use iteration (looping) to repeat actions in your code

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 Coding challenge - Day 246 | What is the output of the following Python Code?

 

x = "hello" * 2

print(x)

String Multiplication:


"hello" is a string.

2 is an integer.

When you multiply a string by an integer, the string is repeated that many times.

In this case, "hello" * 2 produces "hellohello", which is the string "hello" repeated twice.

Assignment:


The result "hellohello" is assigned to the variable x.

Print Statement:


The print(x) statement outputs the value of x, which is "hellohello".

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".

PDF file protection using password in Python

 

from PyPDF2 import PdfReader, PdfWriter
import getpass

def protect_pdf(input_pdf, output_pdf):
    reader = PdfReader('clcoding.pdf')
    writer = PdfWriter()

    for page in reader.pages:
        writer.add_page(page)

    password = getpass.getpass("Enter a password : ")
    writer.encrypt(password)
    with open(output_pdf, "wb") as output_file:
        writer.write(output_file)
    print(f"The PDF has password.")
    
protect_pdf("clcoding.pdf", "protected_file.pdf")

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.

Rainbow Circle using Python

 

import turtle

t = turtle.Turtle()

t.speed(10)

colors = ['red', 'orange', 'yellow',

          'green', 'blue', 'indigo',

          'violet']

turtle.bgcolor('black')

for i in range(36):

    t.color(colors[i % 7])

    t.circle(100)

    t.right(10)

turtle.done()


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.


Wednesday, 6 November 2024

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.


Tuesday, 5 November 2024

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.


Monday, 4 November 2024

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.



Sunday, 3 November 2024

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.
