#Define a function calledget_class_average that has one argumentstudents. You can expect students to be a list containing your three students.
#First, make an empty list calledresults.
#For each student item in the classlist, calculate get_average(student) and then call results.append() with that result.
#Finally, return the result of callingaverage() with results.

def get_class_average(students):
    results = {} //should be results = []
    for item in students:
        results.append(get_average(item))
    return average(results)
