A function is not restricted to return a variable, it can return zero, one, two or more values. To access these values in our main program, we have to use indexing: We use the values[0] syntax to access the first value in the list our calculate_data() function returns. For this reason, the function in the above example returns a tuple with each value as an element. Meaning that if your function expects 2 arguments, you have to call the function with 2 arguments, not more, and not less. See below for a simple example.
