Question 1

Question 1Assertion (A): Each component of a programming statement is known as a token.Reasoning (R): Token is not executed by Python interpreter, only used in the program coding.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.ExplanationA token is the smallest element of a Python script that is meaningful to the interpreter. Each component of a programming statement is referred to as a token. Comments are not executed by the interpreter, but tokens are executed by it.

Question 2

Question 2Assertion (A): The data type of a variable is declared as per the type of value assigned to it.Reasoning (R): Python exhibits the feature of dynamic typing. In dynamic typing, the type of the variable is determined only during runtime.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, we are not required to explicitly declare a variable with its type. Whenever we declare a variable with a value, Python automatically assigns the relevant data type to it based on the assigned value. This process is known as dynamic typing.

Question 3

Question 3Assertion (A): In Python, integers are zero, positive or negative whole numbers without a fractional part.Reasoning (R): -45, 655.55, -1000, 55.89 are the integer values in Python.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.ExplanationInteger represents whole numbers without any fractional part. They can be zero, positive or negative. -45, -1000 are the integer values in Python while 655.55, 55.89 are floating-point numbers.

Question 4

Question 4Assertion (A): In Python, strings, lists and tuples are called sequences.Reasoning (R): Sequence is referred to as an ordered collection of values having similar or different data types.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 sequence is an ordered collection of items in Python, and these items can have similar or different data types. They are indexed by integers. The three main types of sequence data types in Python are strings, lists, and tuples.

Question 5

Question 5Assertion (A): Comments are non-executable statements that enable the users to understand the program logic.Reasoning (R): Comments are basically statements used to put remarks. The comments are used to explain the code and to make it more informative for the users.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.ExplanationComments are statements in a script that are ignored by the Python interpreter. Comments are basically statements used to put remarks and are used to explain the code and to make it more informative for the users. They make the code more readable and understandable for human beings.

Question 6

Question 6Assertion (A): A set of valid characters recognized by Python constitutes a character set.Reasoning (R): Character set in Python is a subset of Python tokens.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.ExplanationCharacter set is a set of valid characters recognized by Python. A character represents any letter, digit or any other symbol present on the keyword. On the other hand, a token is the smallest element of a Python script that is meaningful to the interpreter which includes keywords, identifiers, literals, operators and delimiters/punctuators. A character set can be used to form tokens, but not all tokens are part of the character set.

Question 7

Question 7Assertion (A): 'Rollnumber' and 'rollnumber' are same identifiers.Reasoning (R): Python is a case-sensitive language, i.e., it treats uppercase and lowercase letters differently.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 a case-sensitive language, meaning it distinguishes between uppercase and lowercase letters. Therefore, 'Rollnumber' and 'rollnumber' are not considered the same identifiers in Python.

Question 8

Question 8Assertion (A): Floor division operator (//) in Python is different from division operator.Reasoning (R): Consider the given two statements:>>>10//3 will give the output as 3.On the other hand,>>>10/3 will give the output as 3.3333333333333335Both 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, the floor division operator (//) performs integer division. On the other hand, the division operator (/) performs float division. For example, the statement 10 // 3 will give the output 3, whereas 10 / 3 will give the output 3.3333333333333335.

Question 9
