Machine Learning Random Forest with Python from Scratch - Lists

The video tutorial covers the implementation of the length function for tuples, introduces lists as a mutable data type, and demonstrates various list operations. It explains the differences between tuples and lists, focusing on mutability. The tutorial also explores advanced list manipulations, including replacing elements and handling nested lists. The concept of negative indexing is introduced for accessing list elements. The session concludes with a task for students to practice deleting an element from a list.

What does the length function return when applied to a tuple?

• The sum of all elements

• The type of elements

• The number of elements

• The first element

What is the primary difference between lists and tuples in Python?

• Lists are faster than tuples

• Lists are mutable, tuples are immutable

• Lists can only store numbers, tuples can store any data type

• Lists are immutable, tuples are mutable

How can you update the first element of a list in Python?

• By using the pop method

• By using the append method

• By directly assigning a new value to the first index

• By using the insert method

Why can't you replace a character in a string element of a list?

• Because lists do not support string operations

• Because strings are immutable

• Because strings are mutable

• Because it requires a special method

What method is used to add a new element to the end of a list?

• add()

• insert()

• extend()

• append()

How can you access the last element of a list without counting all elements?

• Using the first() method

• Using the length function

• Using index -1

• Using index 0

What task were students given at the end of the lesson?

• Add a new element to a list

• Sort the list

• Replace a string in a list

• Delete an element from a list
