Data Science and Machine Learning (Theory and Projects) A to Z - Data Structure (List, Tuple, Set, Dictionary): Insertio

The video tutorial covers indexing in Python, focusing on lists and tuples. It explains how indexing in these data structures is similar to string indexing, and discusses the mutability of lists compared to the immutability of tuples. The tutorial also covers how to expand and modify lists, and the operations possible on sets and dictionaries. It highlights the similarities in indexing across different data structures, including Numpy and Pandas, and introduces basic operations like adding, deleting, and modifying elements.

What is a key similarity between indexing in strings and lists?

• Both allow for element deletion.

• Both use zero-based indexing.

• Both require a special library.

• Both are immutable.

How can you reverse a list in Python?

• By slicing with [::-1].

• Using the reverse() function.

• Using the reversed() function.

• By using a for loop.

What happens when you modify a sublist in Python?

• The original list remains unchanged.

• The original list is also modified.

• A new list is created.

• An error is raised.

Which of the following is true about tuples?

• They are mutable.

• You can insert elements directly.

• They are immutable.

• They can be sorted in place.

How can you add multiple elements to a set in Python?

• Using the update() function.

• Using the append() function.

• Using the add() function.

• Using the insert() function.

What is the correct way to delete a key-value pair from a dictionary?

• Using the pop() function.

• Using the del statement.

• Using the remove() function.

• Using the discard() function.

Which function is used to remove an element from a set?

• pop()

• discard()

• remove()

• delete()
