This video tutorial guides viewers through a Python coding exercise focused on functions. It begins with an introduction to the task, which involves completing a function named return_42 to return the value 42. The tutorial then explains how to create another function, my_function, which takes two arguments and returns their product. The video concludes with a review of the solutions and a brief wrap-up of the functions section.

What is the primary task of the 'return_42' function in the exercise?

• To print the number 42

• To calculate the sum of two numbers

• To return the number 42

• To display a message

Why is indentation important when writing the 'return_42' function?

• It is required for the code to be syntactically correct in Python

• It helps in aligning the code with the comments

• It makes the code look neat

• It is necessary for the function to be recognized by the compiler

What is the purpose of the 'my_function' in the exercise?

• To divide two numbers

• To add two numbers

• To subtract two numbers

• To multiply two numbers

How many parameters does 'my_function' take?

• One

• Two

• None

• Three

What ensures that the functions work correctly without being manually called?

• The test code written checks and calls the functions

• The functions are executed by a built-in Python library

• The functions are automatically executed by Python

• The functions are called within the main program
