Understanding Tuples in Python

What is a tuple in Python?

• A tuple is a mutable sequence type in Python.

• A tuple is defined by items in square brackets.

• A tuple can be modified after creation.

• A tuple is an immutable sequence type in Python, defined by items in parentheses.

How do you define a tuple in Python?

• A tuple is defined using square brackets, e.g., [1, 2, 3].

• A tuple is defined using parentheses, e.g., (1, 2, 3).

• A tuple is defined using curly braces, e.g., {1, 2, 3}.

• A tuple is defined using angle brackets, e.g., <1, 2, 3>.

Which of the following is a valid tuple?

• (1; 'a'; 3.14)

• {1, 'a', 3.14, 2}

• [1, 'a', 3.14]

• (1, 'a', 3.14)

Can a tuple contain elements of different data types?

• No, tuples are restricted to a single data type.

• Yes, but only if they are all numbers.

• No, a tuple can only contain elements of the same data type.

• Yes, a tuple can contain elements of different data types.

What is the main difference between a list and a tuple?

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

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

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

• Lists are faster than tuples in all operations.

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

• my_tuple.get(0)

• my_tuple[0]

• my_tuple[1]

• my_tuple.first()

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

• (1, 2, 3, 4)

• (1, 2, 3, 4, 5)

• (1, 2, 3) + (4)

• (1, 2) + 3, 4

Can you change an element of a tuple after it is created?

• Yes, you can change an element of a tuple after it is created.

• Tuples can be modified using indexing.

• You can replace a tuple with a new one that has different elements.

• No, you cannot change an element of a tuple after it is created.

How do you find the length of a tuple?

• Use count(tuple_name) to find the length of a tuple.

• Apply size(tuple_name) to determine the length of a tuple.

• Use len(tuple_name) to find the length of a tuple.

• Invoke length(tuple_name) to get the length of a tuple.

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

• (1, 2, 3, 1, 2, 3, 4)

• (1, 2, 3, 1, 2, 3)

• (1, 2, 3, 1, 2)

• (1, 2, 3, 2)
