Solution to Python quiz problem

quiz1 = int(raw_input("Enter quiz 1 score: "))
quiz2 = int(raw_input("Enter quiz 2 score: "))
quiz3 = int(raw_input("Enter quiz 3 score: "))
# Find the lowest
if quiz1 <= quiz2 and quiz1 <= quiz3:
    lowest = quiz1
elif quiz2 <= quiz1 and quiz2 <= quiz3:
    lowest = quiz2
elif quiz3 <= quiz1 and quiz3 <= quiz2:
    lowest = quiz3

#Even better:
#lowest = min(quiz1, quiz2, quiz3)

print "Dropping the", lowest
average = (quiz1 + quiz2 + quiz3 - lowest) / 2.0

print "Your average is", average

if average >= 90:
    print "Your grade is A"
elif average >= 80:
    print "Your grade is B"
elif average >= 70:
    print "Your grade is C"
elif average >= 60:
    print "Your grade is D"
