Python lists: The basics of a common way to store groups of objects in Python

The video tutorial explains Python lists, a collection type that stores objects in a specific order. It covers list properties, accessing items using indices, including negative indices, and introduces nested lists. The tutorial also discusses iteration using loops, list methods like append and pop, and performance considerations when modifying lists. Finally, it highlights testing for item presence in lists and suggests using dictionaries or sets for efficient membership testing.

What is the starting index for accessing elements in a Python list?

• 1

• 0

• 2

• -1

Which Python function can be used to iterate over a list while also getting the index of each element?

• loop

• index

• iterate

• enumerate

Which method would you use to add an element to the end of a list?

• add

• extend

• append

• insert

Why might inserting elements in the middle of a large list be inefficient?

• It causes a syntax error.

• It automatically sorts the list.

• It is not supported in Python.

• It requires re-indexing all elements.

What is a more efficient alternative to lists for testing membership of an object?

• Integer

• String

• Dictionary

• Tuple
