Python In Practice - 15 Projects to Master Python - Return Values from User-Defined Functions Using the Return Keyword

The video tutorial explains how to use lists and loops to access elements, and how to return values from functions using the return keyword. It demonstrates executing functions, storing results in variables, and using return to output results effectively.

What is the primary purpose of using a for loop with a list?

• To sort the list elements

• To modify the list elements

• To access and iterate over the list elements

• To delete elements from the list

What is the role of the return keyword in a function?

• To store the function's result in a global variable

• To send a value back to the caller of the function

• To stop the function execution

• To print the result of the function

Why might a function not print the sum of numbers directly?

• Because the sum is stored in a database

• Because the sum is too large to display

• Because the sum is returned, not printed

• Because the sum is stored in a file

What should you do with a returned value from a function?

• Ignore it

• Pass it to another function

• Store it in a variable

• Print it immediately

How can you ensure the result of a function is displayed to the user?

• By using the return keyword alone

• By storing the returned value in a variable and printing it

• By calling the function twice

• By using a global variable
