Mastering Python Data Structures

What is the output of the following code: (1, 2, 3) + (4, 5)?

• (1, 2, 3, 5)

• (1, 2, 3, 4, 5)

• (1, 2, 3, 4)

• (1, 2, 3, 4, 5, 6)

How do you access the second element of a tuple named 'my_tuple'?

• my_tuple(1)

• my_tuple[1]

• my_tuple[2]

• my_tuple.get(1)

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

• Tuple slicing

• Item retrieval

• Tuple concatenation

• Item assignment or deletion

What is the result of the expression len((1, 2, 3))?

• 2

• 4

• 3

• 3.5

Write a list comprehension to create a list of squares of numbers from 1 to 10.

• [x*2 for x in range(1, 11)]

• [x**2 for x in range(1, 11)]

• [x^2 for x in range(1, 11)]

• [x**2 for x in range(10)]

What is the difference between a list and a tuple in Python?

• Lists are faster than tuples in all operations.

• Tuples are created using square brackets, while lists use parentheses.

• Lists can only contain numbers, while tuples can contain any data type.

• The main difference is that lists are mutable and tuples are immutable.

How do you convert a list to a tuple?

• list(my_list)

• array(my_list)

• convert(my_list)

• tuple(my_list)

What will be the output of the following code: [x for x in range(5) if x % 2 == 0]?

• [1, 3]

• [0, 2, 4]

• [0, 2, 4, 6]

• [5, 6, 7]

Which of the following data types is mutable?

• Lists and dictionaries are mutable data types.

• Tuples and sets are mutable data types.

• Strings and integers are mutable data types.

• Booleans and floats are mutable data types.

What is the output of the expression {1, 2, 3} | {2, 3, 4}?

• {1, 2, 3} & {2, 3, 4}

• {1, 2, 3, 4}

• {1, 2, 3, 2, 3, 4}

• {2, 3}
