Consider the following program:
def squareArea(sideLength) :   return sideLength ** 2a = squareArea(4)
What are the arguments (actual parameters) in this program?

To start, identify the role of each term in a function call. A parameter (or formal parameter) is the variable listed in the function definition, while an argument (actual parameter) is the value supplied when the function is invoked.

In this program, the function is defined as squareArea(sideLength), so sideLength is the parameter name. The call a = squareArea(4) provides the value 4 as the argument to that parameter. Therefore, the actual parameter being passed here is the literal value 4.

If we separate the concepts clearly: the argument is the actual value used in the call (4), and the corresponding formal parameter receiving it in the function is sideLength. The code snippet does not pass any additional values beyond this single literal, so there is only one actual parameter in this invocation.

Even though there is a minor potential formatting issue in the snippet (the return line and the following line may appear concatenated in the text), the intended interpretation remains that squareArea is called with a single value, 4, as its argument.
