The video tutorial explains the concept of boolean functions, which return true or false, and value returning functions, which return one or more values. It provides examples of both types of functions, including a boolean function that checks if a number is even and a value returning function that joins two names. The tutorial demonstrates how to implement these functions in Jupiter, offering clarity on their operation.

What is a boolean function?

• A function that returns a string

• A function that returns true or false

• A function that returns a number

• A function that does not return any value

Which of the following is an example of a value returning function?

• A function that prints a message

• A function that returns a boolean value

• A function that returns a calculated ratio

• A function that does not return any value

What condition does the boolean function 'isEven' check?

• If a number is negative

• If a number is divisible by 2

• If a number is odd

• If a number is greater than 10

What will the 'isEven' function return for the input 5?

• 5

• True

• None

• False

What is the purpose of the 'joinName' function?

• To return a boolean value

• To calculate the sum of two numbers

• To join two strings with a space

• To check if a number is even

What will the 'joinName' function return for the inputs 'Sajjad' and 'Mustafa'?

• Sajjad, Mustafa

• Mustafa Sajjad

• Sajjad Mustafa

• SajjadMustafa

How can the result of the 'joinName' function be stored?

• By using it in a loop

• By converting it to a number

• By assigning it to a variable

• By printing it directly
