Beginning Python (Video 30)

The video tutorial explains the difference between return and void functions in programming. Return functions use the return keyword to provide a value that can be assigned to a variable, while void functions perform actions without returning a value. Examples of return functions include max and length, whereas void functions include print and sort. The tutorial provides examples of both types of functions, such as an 'is even' function that returns a boolean value and a void version that prints the result. The video concludes with a summary and a preview of the next topic.

What is the primary characteristic of a return function?

• It uses the return keyword to provide a value.

• It performs an action without returning a value.

• It always prints output to the console.

• It modifies data in place without returning anything.

Which of the following is an example of a return function?

• insert()

• len()

• sort()

• print()

What does a void function typically do?

• Calculates and returns a numeric result.

• Returns a value that can be assigned to a variable.

• Performs an action without returning a value.

• Always returns a boolean value.

Which function is an example of a void function?

• max()

• print()

• len()

• split()

How would a void version of the 'is even' function behave?

• It would modify the number to be even.

• It would return the number itself.

• It would print whether the number is even or odd.

• It would return true or false.
