Question 1

Question 1Assertion (A): When a set of statements is indented under the same block, starting from the same indentation, it is said to be a compound statement.Reasoning (R): Compound Statement begins with a header ending with a colon (:) sign and the statements under the same indentation are marked as a block.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 and R is the correct explanation of A.ExplanationA compound statement in Python is formed when multiple statements are grouped together under the same block of indentation. The header line begins with a keyword and ends with a colon (:). Subsequent statements that are indented under the same level are considered part of the block.

Question 2

Question 2Assertion (A): The conditional flow of control is implemented using if statement.Reasoning (R): A statement or statements (block of code) are indented (usually 4 spaces) inside the if statement and are executed only if the condition evaluates to true, otherwise they are ignored.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 and R is the correct explanation of A.ExplanationThe if statement in Python allows conditional flow of control. It evaluates a condition and executes one or more statements based on whether the condition is true or false. If the condition evaluates to true, the statement block following the if statement (indented code) gets executed, otherwise, if the condition is false, that block is skipped, and the program continues with the next statement after the if block.

Question 3

Question 3Assertion (A): In an if-else statement, the if block checks the true part whereas else checks for the false part.Reasoning (R): In a conditional construct, else block is mandatory.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.ExplanationIn an if-else statement, the if block checks if a condition is true and will execute a block of statements and if the condition is false, it won't execute that block. The else part executes a block of code when the if condition is false. In a conditional construct, the else block is not mandatory.

Question 4

Question 4Assertion (A): When a Python code is unable to accept an input, it results in runtime error.Reasoning (R): Runtime error arises due to incorrect statement that results in no output.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.ExplanationWhen a Python code is unable to accept an input, it results in a runtime error. Runtime errors arise due to issues that occur while the program is running, such as attempting to use invalid operations on data types. In contrast, syntax error arises due to incorrect statement that results in no output.

Question 5

Question 5Assertion (A): The break and continue statements are known as jump statements.Reasoning (R): Jump statements are used only with looping constructs and not with conditional constructs.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 and R is the correct explanation of A.ExplanationIn Python, break and continue are categorized as jump statements because they alter the flow of control in loops. Jump statements, such as break and continue, are used within loop constructs to control the flow of execution. Python does not have a switch-case conditional construct. Hence, in Python, jump statements are not used with conditional constructs.

Question 6

Question 6Assertion (A): The range() method is used with both for and while loops.Reasoning (R): By default, the values for start and step are 0 (zero) and 1 (one), respectively.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.ExplanationThe range() function is used with for loops to iterate over a sequence of numbers, not with while loops. By default, the values for start and step are 0 (zero) and 1 (one), respectively.

Question 7

Question 7Assertion (A): The for loop is described as finite loop and while loop is described as unknown or indefinite iterative construct.Reasoning (R): You cannot use while loop for menu-driven programs.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 for loop is described as a finite loop because it iterates over a sequence of elements with a known length. The while loop is described as an indefinite iterative construct because it continues to execute as long as a condition is true, without a predetermined number of iterations. We can use a while loop for menu-driven programs to repeatedly display a menu and process user input until a certain condition is met.

Question 8

Question 8Assertion (A): Indentation is a very important factor while writing a program in Python.Reasoning (R): Indentation refers to the spaces at the beginning of a code line. Multiple statements with the same indent are classified as a block of code.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 and R is the correct explanation of A.ExplanationIndentation is a very important factor while writing a program in Python because it defines the structure and grouping of code blocks. Indentation refers to the spaces at the beginning of a code line, and multiple statements with the same indent level are classified as a block of code.

Question 9

Question 1Statements in Python are executed sequentially while working with a sequence construct.
