Q: Question 12"Decomposition leads to simplicity." How?

Decomposition is the process of breaking down a complex problem or system into smaller, easily manageable parts. These smaller problems are solved one after the other until the bigger complex problem is resolved. This stage involves breaking down the problem into smaller components so that they can be tackled more easily. The more we can break down a problem, the easier it is to solve.

Q: Question 13Write an algorithm to find a factorial of an inputted number.

Step 1: StartStep 2: Input the number "n" from the user.Step 3: Initialize a variable "fact" to 1.Step 4: If n is 0, then the factorial is 1 and go to Step 7.Step 5: If "n" is greater than 0, multiply "fact" by each integer from 1 to "n" in sequence.Step 6: The final value of "fact" is the result.Step 7: Display "fact".Step 8: End

Question 1

Question 3Assertion (A): The interactive mode of Python gives instant result of the typed statement.Reasoning (R): Script mode is an interactive window where Python code can be executed in the same window.Both A and R are true and R is the correct explanation of A.Both A and R are true but R is not the correct explanation of A.A is true but R is false.A is false but R is true.

Accepted Answer

A is true but R is false.ExplanationThe interactive mode of Python gives instant results for typed statements. The Python Shell is an interactive window where you can type in Python code and see the output immediately in the same window. It serves as an interface between Python commands and the operating system.

Question 2

Question 7Assertion (A): Python is the fastest language.Reasoning (R): Python is an interpreted language.Both A and R are true and R is the correct explanation of A.Both A and R are true but R is not the correct explanation of A.A is true but R is false.A is false but R is true.

Accepted Answer

A is false but R is true.ExplanationPython is not considered the fastest programming language as it is slower than many compiled languages such as C or C++ because it is interpreted rather than compiled. Python is an interpreted language, which means that Python code is executed line by line at runtime by an interpreter, without the need for a separate compilation step to machine code.

Question 3

Question 8Assertion (A): Python is a case-sensitive language.Reasoning (R): Python is easy to understand as it has a clearly defined syntax and simple structure.Both A and R are true and R is the correct explanation of A.Both A and R are true but R is not the correct explanation of A.A is true but R is false.A is false but R is true.

Accepted Answer

Both A and R are true but R is not the correct explanation of A.ExplanationPython is a case-sensitive language. This means that Python differentiates between capital and small alphabets. Python programs use clear, simple, concise instructions and clearly defined syntax and simple structure that are easy to read and understand even by non-programmers.

Question 4

Question 9Which of the following codes is correct?1.print("Programming is fun")
print("Python") 
print("Computer Science")
2.print ("Programming is fun)
print("Python") 
print("Computer Science)
3.Print("Programming is fun")
print("Python") 
print("Computer Science")
4.Print("Programming is fun")
Print("Python") 
Print("Computer Science")

Accepted Answer

print("Programming is fun")
print("Python") 
print("Computer Science")
Reason — In Python, the print() function is written in lowercase (print) and strings must be enclosed in matching pairs of either single (') or double quotes ("). Therefore, the correct code would be :print("Programming is fun")
print("Python") 
print("Computer Science")

Question 5

Question 2Write some limitations of Python.

Accepted Answer

Some limitations of Python programming language are:Not the Fastest Language — As Python is an interpreted language so its execution-times are not that fast compared to some compiled languages.Lesser Libraries than C, Java, Perl — Library collection of C, Java, Perl is better than Python.Not strong on Type-Binding — Python interpreter is not very strong on catching 'Type-Mismatch' issues.Not easily convertible — Translating Python programs to other languages is difficult due to its lack of syntax.

Question 6

Question 6Two friends decide who gets the last slice of a cake by flipping a coin five times. The first person to win three flips wins the cake. An input of 1 means player 1 wins a flip, and a 2 means player 2 wins a flip. Design an algorithm to determine who takes the cake?

Accepted Answer

Step 1: Initialize Counters:

SET p1 = 0
SET p2 = 0

Step 2: Process Coin Flips:

FOR each flip from 1 to 5
        INPUT result
        IF result is 1 THEN
            INCREMENT p1
        ELSE IF result is 2 THEN
            INCREMENT p2
        IF p1 is 3 THEN
            PRINT "Player 1 wins the cake."
            EXIT the algorithm
        ELSE IF p2 is 3 THEN
            PRINT "Player 2 wins the cake."
            EXIT the algorithm

Question 10Write an algorithm that performs the following:Ask a user to enter a number.If the number is between 5 and 15, write the word GREEN.If the number is between 15 and 25, write the word BLUE.If the number is between 25 and 35, write the word ORANGE.If it is any other number, write that ALL COLORS ARE BEAUTIFUL.

Accepted Answer

Step 1: INPUT number

Step 2:

IF number is between 5 and 15 THEN
    PRINT "GREEN"
ELSE IF number is between 15 and 25 THEN
    PRINT "BLUE"
ELSE IF number is between 25 and 35 THEN
    PRINT "ORANGE"
ELSE
    PRINT "ALL COLORS ARE BEAUTIFUL"

Question 8

Question 11Write an algorithm that accepts four numbers as input and find the largest and smallest of them.

Accepted Answer

Step 1: INPUT num1, num2, num3, num4 Step 2: SET largest = num1 Step 3: SET smallest = num1 Step 4: IF num2 > largest THEN Step 5: SET largest = num2 ELSE IF num2 < smallest THEN Step 6: SET smallest = num2 Step 7: IF num3 > largest THEN Step 8: SET largest = num3 ELSE IF num3 < smallest THEN Step 9: SET smallest = num3 Step 10: IF num4 > largest THEN Step 11: SET largest = num4 ELSE IF num4 < smallest THEN Step 12: SET smallest = num4 Step 13: PRINT "The largest number is: " + largest Step 14: PRINT "The smallest number is: " + smallest

Question 15Write the pseudocode to print the bill depending upon the price and quantity of an item. Also, print Bill GST, which is the bill after adding 5% tax in the total bill.

Accepted Answer

Step 1: INPUT price
Step 2: INPUT quantity

Step 3: COMPUTE total_bill = price * quantity

Step 4: COMPUTE gst_amount = total_bill * 0.05

Step 5: COMPUTE bill_with_gst = total_bill + gst_amount

Question 16

Question 19What is IDLE?

Accepted Answer

IDLE is a simple Integrated Development and Learning Environment that comes with Python. The most important feature of IDLE is that it is a program that allows the user to edit, run, browse and debug a Python program from a single interface.

Question 17

Question 20Differentiate between displaying and printing method in Python.

Accepted Answer

Printing in Python refers to using the print() function to output information to the console. The print() function takes one or more arguments, converts each argument to a string (if necessary), and displays them as text. On the other hand, displaying can be a more general term that encompasses presenting information or output in various forms, not limited to just text output in the console.

Question 18

Question 21Briefly explain the salient features of Python.

Accepted Answer

The salient features of Python are as follows:Python is an interpreted, interactive, directly executed language with a pre-compiled code. This means that it is processed at runtime by the interpreter and we need not compile our program before executing it.It is a loosely type object-oriented programming language with a few keywords, simple English-like structure and is easy to learn.It is a free, open-source and portable language having a large repository of libraries.It takes less time to develop as Python programs are typically 3 to 5 times shorter than the equivalent programming languages. This is because of its built-in, high-level data types and its dynamic typing.It is extensible/extendable and highly efficient as there is no wastage of time in declaring the types of variables or arguments.It supports GUI (Graphical User Interface) and garbage collection (better memory management).It is easily compatible with other languages like C, C++, Core Java etc.Python is used for both scientific and non-scientific programming.
