In the preceding gradeCenter() function, we defined gradeCenter() to require a value for the variable score. Once we called the function and gave it the information (the assignment’s score), it printed the correct exercise information.
The variable score in the definition of gradeCenter() is an example of a parameter, a piece of information the function needs to do its job. The value ” - Score 100” is an example of an argument. An argument is a piece of information that is passed from a function call to a function. When we call the function, we place the value we want the function to work with in parentheses. In this case the argument ” - Score 100” was passed to the function gradeCenter(), and the value was stored in the parameter Score.
