# The first version of a program that tracks the grades for a class.
# (This version employs an inappropriate implementation and is used only
# for illustration purposes only - what could be done with an array/list).

# Global constant
CLASS_SIZE = 5

# Get class data
stu1 = float(input("Enter grade for student no. 1: "))
stu2 = float(input("Enter grade for student no. 2: "))
stu3 = float(input("Enter grade for student no. 3: "))
stu4 = float(input("Enter grade for student no. 4: "))
stu5 = float(input("Enter grade for student no. 5: "))

#Calculate pertinent statistics
total = stu1 + stu2 + stu3 + stu4 + stu5
average = total / CLASS_SIZE

# Display results
print()
print("GRADES")
print("The average grade is %.2f%%" %average)
print("Student no. 1: %.2f" %stu1)
print("Student no. 2: %.2f" %stu2)
print("Student no. 3: %.2f" %stu3)
print("Student no. 4: %.2f" %stu4)
print("Student no. 5: %.2f" %stu5)
