Beginning Python (Video 11)

This video introduces the list data structure in Python, covering how to create lists, access elements using indexes, and delete elements. It also compares lists with strings, highlighting their similarities and differences, particularly focusing on mutability. The video sets the stage for more advanced list methods and functions in future lessons.

What is the correct way to create a list of numbers in Python?

• numbers = <1, 2, 3>

• numbers = {1, 2, 3}

• numbers = (1, 2, 3)

• numbers = [1, 2, 3]

How are elements in a Python list accessed?

• Using parentheses ()

• Using angle brackets <>

• Using curly braces {}

• Using square brackets []

What will happen if you try to access an index that does not exist in a list?

• The last element will be returned

• The program will crash

• A default value will be returned

• An IndexError will be raised

Which keyword is used to remove an element from a list at a specific index?

• remove

• delete

• discard

• pop

After deleting an element from a list, what happens to the list?

• The list remains unchanged

• The list becomes longer

• The list becomes shorter

• The list is reset to empty

How are strings and lists similar in Python?

• Both are immutable

• Both can be indexed

• Both can be concatenated

• Both can be sorted

Why are strings considered immutable in Python?

• Because they are stored in a different memory space

• Because they cannot be indexed

• Because they cannot be changed after creation

• Because they can only contain characters
