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.

Provide an example of a void function and describe its purpose.

How would you modify a function that checks if a number is even to make it a void function?
