can anyone help me pls. The mistake is: Oops, try again. It looks like not all grades were printed! Make sure you are printing ech one on their own line".

grades = [100, 100, 90, 40, 80, 100, 85, 70, 90, 65, 90, 85, 50.5]

def print_grades(grades):
    for grade in grades:
        print print_grades(grades)

def grades_sum(grades):
    total = 0
    for grade in grades: 
        total += grade
    return total
    print grades_sum(grades)
    
def grades_average(grades):
    sum_of_grades = grades_sum(grades)
    average = sum_of_grades / float(len(grades))
    return average
    print grades_average(grades)

def grades_variance(scores):
    average = grades_average(scores)
    variance = 0
    for score in scores:
        variance += (average - score) ** 2
        g = variance / len(scores)
    return g
    print grades_variance(grades)

def grades_std_deviation(variance):
    return variance ** 0.5
variance = grades_variance(grades)
print grades_std_deviation(variance)

What's stopping you?

you need to print them all out individually with
print (function)
