Question 1

Question 1Assertion (A): List in Python is a collection of values of any type.Reasoning (R): In lists, you can change the elements of a list in place.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.ExplanationList in Python is a collection of values of any type such as strings, integers, floats, objects or even a list. Lists in Python are mutable, meaning we can change the elements of a list in place.

Question 2

Question 2Consider the given two statements:T1 = [3, 9, 0, 1, 7]T2 = [5, 1, 0, 7, 5.5]Assertion (A): Output of print(len(T1) == len(T2)) is True.Reasoning (R): The len() function returns the number of elements in the list. If two lists have same number of elements, then == operator will return True.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 output of print(len(T1) == len(T2)) is True because both T1 and T2 have the same number of elements (5 elements each). The len() function returns the length of the list, i.e., the number of elements in a list.

Question 3

Question 3Assertion (A): List traversal in Python is done through slicing and using for loop also.Reasoning (R): Traversal can be done only through forward indexing.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.ExplanationList traversal in Python can be done using slicing and a for loop. Both methods allow to access and iterate over elements in a list. Traversal in Python lists can be done through both forward and backward indexing.

Question 4

Question 4Assertion (A): In Python, list is an immutable collection of data.Reasoning (R): Mutable means that any change or alteration in data is mentioned in the same place. The updated collection will use the same address for its storage.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.ExplanationIn Python, list is a mutable collection of data, i.e., values in the list can be modified. The term "mutable" means that the objects can be changed in place, and any modifications to the object will use the same memory address.

Question 5

Question 5Assertion (A): The position of each element in the list is considered as its index.Reasoning (R): Indexing in a list can be positive and negative; index is defined using [] brackets.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, an index is a number specifying the position of an element in a list. Indexing in a list can be positive and negative. Positive indexing starts from 0 for the first element, while negative indexing starts from -1 for the last element. Indexing is defined using square brackets ([]).

Question 6

Question 6Assertion (A): sort() method sorts the objects of list in ascending order.Reasoning (R): Defining sort() method with reverse=True as an argument sorts the list elements in descending order.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 sort() function sorts the items of the list, by default in ascending/increasing order. If we want to sort the list in decreasing order, we need to write: sort(reverse = True).

Question 7

Question 7Assertion (A): An empty list can be created using list() method.Reasoning (R): The following snippet—>>>L1 = list()
>>>print(L1)
will give the output as:[]This statement holds true.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.ExplanationAn empty list can be created using list() method. The provided code:>>>L1 = list()
>>>print(L1)
will give the output as: [], which represents an empty list.

Question 8

Question 8Assertion (A): List is mutable data type.Reasoning (R): In-place change is not possible in list elements.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 Python, list is an mutable data type, i.e., values in the list can be modified. In-place changes are possible in list elements. We can modify, add, or remove elements in a list directly.

Question 9

Question 9Assertion (A): List slices are the sub-part of a list extracted out.Reasoning (R): In Python, Slice operator[:] is used to select a range of elements from a sequence.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.ExplanationList slices are the sub-parts of a list extracted out. In Python, Slice operator[:] is used to select a range of elements from a sequence. The syntax used for slicing is: list[start:stop:step].

Question 10

Question 1List in Python is classified as a Sequence data type.
