Create a list : Lists in Python

The video tutorial introduces lists in Python, explaining their advantages over using multiple variables. It covers how to create lists, access elements, and the importance of keeping data homogeneous. The tutorial also discusses nested lists and demonstrates list operations like append and remove. The video concludes with a preview of future topics, emphasizing the utility of lists in programming.

What is a primary advantage of using lists over multiple variables?

• Lists automatically sort data.

• Lists are easier to read than variables.

• Lists allow for faster computation.

• Lists can store multiple values in a single variable.

How do you access the first element of a list named 'friends'?

• friends[-1]

• friends[1]

• friends[first]

• friends[0]

Why is it recommended to keep data in a list homogeneous?

• To allow for automatic sorting.

• To avoid confusion and maintain consistency.

• To ensure faster processing.

• To make the list easier to read.

Which function is used to find the number of elements in a list?

• size()

• count()

• length()

• len()

What is a nested list?

• A list that contains other lists as its elements.

• A list that is empty.

• A list that is sorted in ascending order.

• A list that contains only numbers.

How do you add an element to the end of a list?

• list.add(element)

• list.append(element)

• list.insert(element)

• list.push(element)

What happens if you try to remove an element that doesn't exist in a list?

• The first element is removed instead.

• An error is raised.

• The last element is removed instead.

• The list remains unchanged.
