Machine Learning Random Forest with Python from Scratch - Tuples

The video tutorial covers string operations such as finding the starting index of a substring and converting strings to uppercase. It then introduces tuples, explaining their immutability and how they differ from arrays by allowing multiple data types. The tutorial demonstrates tuple operations, highlighting their immutability limitations. Finally, an assignment is given to explore tuple documentation and implement a method.

What is the starting index of the word 'word' in the given string example?

• 8th index

• 7th index

• 6th index

• 5th index

Which method is used to convert a string to uppercase in Python?

• toUpperCase()

• upper()

• convertToUpper()

• makeUpperCase()

What is a key characteristic of tuples in Python?

• They can only store strings.

• They are immutable.

• They are mutable.

• They can only store integers.

How can you define a tuple in Python?

• Using curly braces {}

• Using parentheses ()

• Using angle brackets <>

• Using square brackets []

What happens if you try to change an element of a tuple?

• An error is raised.

• The element is ignored.

• The element is changed successfully.

• The tuple is converted to a list.

In the example, what type of data is stored at index 1 of the tuple?

• Integer

• String

• Float

• Boolean

What is the assignment given at the end of the lecture?

• Implement a new data type.

• Read the documentation of tuples and implement a method.

• Create a mutable tuple.

• Convert a tuple to a list.
