Question 1

Question 1Assertion (A): Tuple in Python is an ordered and immutable data type.Reasoning (R): Tuples can contain heterogenous data and permit duplicate values as well.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.ExplanationTuples in Python are ordered, meaning elements are arranged in a specific sequence, and this order cannot be changed. Tuples are immutable, so once a tuple is created, we cannot add, change, or update its elements. Duplicate values can be included in a tuple. Additionally, a tuple can hold values of different data types, making it heterogeneous in nature.

Question 2

Question 2Consider the given two statements:Statement 1: t1 = tuple('python')Statement 2: t1[4] = 'z'Assertion (A): The above code will generate an error.Reasoning (R): Tuple is immutable by nature.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 statement t1 = tuple('python') creates a tuple t1 from the string 'python', resulting in t1 being ('p', 'y', 't', 'h', 'o', 'n'). The statement t1[4] = 'z' attempts to modify the element at index 4 of the tuple, which is not allowed because tuples are immutable in Python. Hence, it raises an error.

Question 3

Question 3Assertion (A): In Python, tuple is an immutable sequence of data.Reasoning (R): Immutable 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 true but R is false.ExplanationIn Python, tuples are immutable or unmodifiable, so once a tuple is created, we cannot add, change, or update its elements.

Question 4

Question 4Consider the given statements for creating dictionaries in Python:D1 = { 'A' : 'CS' , 'B' : ' IP' }D2 = { 'B' : 'IP', 'A' : 'CS ' }Assertion (A): Output of print(D1==D2) is True.Reasoning (R): Dictionary is a collection of key-value pairs. It is not 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 but R is not the correct explanation of A.ExplanationThe output of print(D1 == D2) is True. In Python, dictionaries are considered equal if they have the same keys and corresponding values, regardless of the order of the key-value pairs. Since D1 and D2 have the same keys with the same values, the comparison returns True. Dictionary is a collection of key-value pairs. It is not a sequence.

Question 5

Question 5Assertion (A): Dictionaries are enclosed within curly braces { }.Reasoning (R): The key-value pairs are separated by commas (,).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.ExplanationDictionaries in Python are enclosed within curly braces {}, where each key is separated from its corresponding value by a colon (:), and different key-value pairs are separated by commas.

Question 6

Question 6Assertion (A): The pop() method can be used to delete elements from a dictionary.Reasoning (R): The pop() method deletes the key-value pair and returns the value of deleted element.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 pop() method is used to delete elements from a dictionary. This method not only deletes the item specified by the key from the dictionary but also returns the deleted value.

Question 7

Question 7Assertion (A): Keys of the dictionaries must be unique.Reasoning (R): The keys of a dictionary can be accessed using values.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 keys of dictionaries in Python must be unique and immutable. Values in a dictionary can be accessed using their corresponding keys.

Question 8

Question 8Assertion (A): clear() method removes all elements from the dictionary.Reasoning (R): len() function cannot be used to find the length of a dictionary.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 clear() method removes all items from the particular dictionary and returns an empty dictionary. The len() method returns the length of key-value pairs in the given dictionary.

Question 9

Question 1Elements in a tuple can be of Dissimilar type.
