Q: Question 3Consider two tuples given below:tup1 = (1, 2, 4, 3) tup2 = (1, 2, 3, 4) What will the following statement print: print (tup1 < tup2)TrueFalseErrorNone of these

FalseReason — In tuple, the comparison operator starts by comparing the first element from each sequence. If they are equal, it goes on to the next element, and so on, until it finds elements that differ. Since tup1 is (1, 2, 4, 3) and tup2 is (1, 2, 3, 4), the third element of tup1 (which is 4) is greater than the third element of tup2 (which is 3). Hence, tup1 is not less than tup2, so the comparison evaluates to False.

Q: Question 14What will be the output?D1 = { "Rahul":56, "Virat":99} print("virat" in D1)TrueFalseNo outputError

FalseReason — In Python, dictionary keys are case-sensitive. The dictionary D1 has the key "Virat" with an uppercase 'V', but the check is for "virat" with a lowercase 'v'. Since "virat" does not match the case of the key "Virat", the expression "virat" in D1 evaluates to False.

Q: Question 2What are the similarities and differences between tuples and lists?

Similarities:Both tuples and lists maintain the order of elements.Both support indexing and slicing to access and manipulate subsets of their elements.Both can store elements of different data types, including numbers, strings, and other objects.Both tuples and lists can be iterated over using loops.Differences:Tuples are immutable, while lists are mutable.Tuples are enclosed in parentheses (), while lists are enclosed in square brackets [].Tuples use less memory whereas lists use more memory.We can use tuples in dictionary as a key but it is not possible with lists.We cannot sort a tuple but in a list we can sort by calling "list.sort()" method.We cannot remove an element in a tuple but in list we can remove an element.We cannot replace an element in a tuple but we can replace in a list.

Q: Question 4What are the differences between tuple and dictionary?

TupleDictionaryTuples are ordered collection of elements.Dictionaries are unordered collection of key-value pairs.Tuples are immutable.Dictionaries are mutable.Tuples are enclosed in parentheses ().Dictionaries are enclosed in curly braces {}.Elements of tuples can be accessed by index.The items in a dictionary are accessed by keys.

Q: Question 5What are the differences between strings and tuples?

StringsTuplesA sequence of characters used to represent text.An ordered collection of elements that can include different data types.Strings are defined using single quotes ' ', double quotes " ", or triple quotes ''' ''' for multi-line strings.Tuples are defined using parentheses ().

Q: Question 7What is nested tuple? Explain with example.

A nested tuple is a tuple that contains other tuples as its elements. When we add one or more tuples inside another tuple, the items in the nested tuples are combined together to form a new tuple.For example,tuple1 = (0, 1, 2, 3) tuple2 = ('python', 'book') tuple3 = (tuple1, tuple2) print(tuple3)Output((0, 1, 2, 3), ('python', 'book'))

Q: Question 9Write a Python program to create a tuple with different data types and display.

t = tuple((42, "Hello, World!", 3.14, True, [1, 2, 3])) print(t)Output(42, 'Hello, World!', 3.14, True, [1, 2, 3])

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 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 3

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 3Consider two tuples given below:tup1 = (1, 2, 4, 3) 
tup2 = (1, 2, 3, 4) What will the following statement print: print (tup1 < tup2)TrueFalseErrorNone of these

Accepted Answer

FalseReason — In tuple, the comparison operator starts by comparing the first element from each sequence. If they are equal, it goes on to the next element, and so on, until it finds elements that differ. Since tup1 is (1, 2, 4, 3) and tup2 is (1, 2, 3, 4), the third element of tup1 (which is 4) is greater than the third element of tup2 (which is 3). Hence, tup1 is not less than tup2, so the comparison evaluates to False.

Question 10Which function is used to remove all items from a particular dictionary?clear()pop()delete()rem()

Accepted Answer

clear()Reason — The clear() function is used to remove all items from the particular dictionary and returns an empty dictionary.
