Machine Learning Random Forest with Python from Scratch - Introduction to Data Types

The video tutorial introduces six data types in Python: numbers, strings, lists, dictionaries, tuples, and sets. It categorizes them into mutable and immutable types, explaining the differences with examples. Mutable types (lists, dictionaries, sets) can be changed after creation, while immutable types (numbers, strings, tuples) cannot. The tutorial discusses use cases for each type, suggesting immutable types for static data and mutable types for data that may change. The session concludes with a summary and a preview of the next lecture, which will focus on practicing with numbers in a Jupyter notebook.

Which of the following is a mutable data type in Python?

• List

• Number

• Tuple

• String

What is a key characteristic of mutable data types?

• They are always faster to access.

• They cannot be changed after creation.

• They are always stored in a fixed memory location.

• They can be changed after creation.

Which analogy is used to describe mutable data types?

• A locked door

• Building blocks

• A flowing river

• A wall of bricks

What is a key characteristic of immutable data types?

• They cannot be changed after creation.

• They are always faster to access.

• They can be changed after creation.

• They are always stored in a fixed memory location.

Which of the following is an example of an immutable data type?

• List
