Question 1: Which of the following correctly creates a tuple in Python?

1. my_tuple = (1, 2, 3)
2. my_tuple = [1, 2, 3]
3. my_tuple = {1, 2, 3}
4. my_tuple = 1, 2, 3

Question 2: What will be the output of the following code?

my_tuple = (1, 2, 3, 4)
print(my_tuple[2])

1. 1
2. 2
3. 3
4. 4

Question 3: Which of the following operations is not allowed on a tuple?

2. Slicing the tuple
3. Modifying an element
4. Iterating over the tuple

Question 4: Which of the following statements about tuples are true? (Choose all that apply)

1. Tuples are immutable.
2. Tuples can contain different data types.
3. Tuples support indexing and slicing.
4. Tuples are mutable and can be modified.

Question 5: Which of the following correctly slices a tuple my_tuple to get the elements (2, 3)? (Choose two)

1. my_tuple[1:3]
2. my_tuple[1:2]
3. my_tuple[-3:-1]
4. my_tuple[2:4]

Question 6: Tuples are __________, meaning their elements cannot be changed after they are created.

Question 7: The syntax for creating a tuple with a single element requires a __________ after the element.

Question 8: Arrange the following code snippets in the correct order to create and slice a tuple:

• print(sliced_tuple)
• my_tuple = (10, 20, 30, 40, 50)
• sliced_tuple = my_tuple[1:4]

Question 9: Arrange the following code snippets in the correct order to access the last element of a tuple:

• print(last_element)
• my_tuple = (100, 200, 300, 400)
• last_element = my_tuple[-1]

Question 10: Complete the code to create a tuple containing the elements 5, 10, 15:

my_tuple = __________

Question 11: Complete the code to slice a tuple to get the elements (2, 4) from my_tuple:

sliced_tuple = my_tuple[__________]

Question 12: Insert the correct code to create a tuple with a single element 5:

single_element_tuple = __________

Question 13: Insert the correct code to access the second element of a tuple named data:

second_element = __________

Question 14: Rearrange the code to create a tuple with the elements 100, 200, 300 and print the first element:

• print(first_element)
• numbers = (100, 200, 300)
• first_element = numbers[0]

Question 15: Organize the steps to slice a tuple my_tuple to get the last two elements:

• sliced_tuple = my_tuple[-2:]
• print(sliced_tuple)
• my_tuple = (1, 2, 3, 4, 5)

Question 16: What does the following code output?

my_tuple = (10, 20, 30, 40)
print(my_tuple[-3])

1. 10
2. 20
3. 30
4. 40

17. What does the following code output?

my_tuple = (5, 10, 15)
my_tuple[1] = 20
print(my_tuple)

1. (5, 20, 15)
2. (5, 10, 15)
3. Error
4. (5, 10)

Question 18: Tuples can be indexed and sliced just like lists.

1. True
2. False

Question 19: A tuple can be created without using parentheses.

1. True
2. False

Question 20: What happens if you try to slice a tuple with an out-of-range index?

1. It raises an IndexError.
2. It raises a ValueError.
3. It returns an empty tuple.
4. It returns None.

Question 21: Which of the following statements about tuple immutability is correct?

1. Tuple elements cannot be modified, but they can be replaced.
2. Tuple elements can be modified if they are mutable types.
3. Tuples are fully immutable and cannot be changed after creation.
4. Tuples can be modified if they contain only integers.

Question 22: Which of the following expressions correctly slices a tuple my_tuple to get all elements except the first one?

1. my_tuple[1:]
2. my_tuple[:-1]
3. my_tuple[0:]
4. my_tuple[:1]

Question 23: Indexing a tuple returns the element at the specified __________.

Question 24: Tuples are often used to store __________ data that should not be changed.

Question 25: What is the output of the following code?

numbers = (1, 2, 3, 4, 5)
print(numbers[2:4])

1. (2, 3)
2. (3, 4)
3. (4, 5)
4. (1, 2, 3)
