Intro To Python Programming - Function Returns in Python

The video tutorial explains the importance of using parameters in Python functions and avoiding specific implementations within them. It demonstrates how to define a function to calculate the average of two numbers and emphasizes returning values instead of printing them. The tutorial also shows how to use returned values in various contexts, such as storing them in variables or printing them. Additionally, it highlights the flexibility of using functions within print statements and encourages the habit of creating functions that return values to the caller.

Why is it beneficial to have functions return values instead of printing them directly?

• It allows for more flexible use of the function's output.

• It makes the code run faster.

• It reduces the number of lines of code.

• It prevents errors in the code.

What is the purpose of the 'average' function defined in the tutorial?

• To print the sum of two numbers.

• To multiply two numbers.

• To calculate and return the average of two numbers.

• To find the maximum of two numbers.

How do you ensure that user input is treated as an integer in Python?

• By using the str() function.

• By using the input() function.

• By using the int() function.

• By using the float() function.

What happens if you call a function that returns a value but do not store or use the returned value?

• The returned value will be lost.

• The program will crash.

• The function will not execute.

• The function will print the value automatically.

Which of the following is a correct way to use a function's returned value in a print statement?

• average(61, 1008) print()

• print = average(61, 1008)

• average = print(61, 1008)

• print(average(61, 1008))

What is the advantage of using functions that return values in programming?

• They make the code more readable.

• They allow for the reuse of the function's output in different contexts.

• They eliminate the need for variables.

• They automatically optimize the code.

What is the result of calling the average function with inputs 61 and 1008?

• 0

• 1008

• 61

• 534.5
