Question

Hello I am fairly new to python and would like to know where my program is failing and why.. thanks, the basic coding is as follows,

    grade = 0
    total = 0
    scorecount = 0
    while grade >=0:
        grade = raw_input("enter grade ->")
        grade = int(grade)
        total = total + grade
        total = int(total)
        scorecount = scorecount + 1
        scorecount= int(scorecount)
    average = total/scorecount
    print average

Answer 1

You accept the grade, then add it to the average even if it is -1, since you don’t check for -1 until the loop starts again.

To quit a loop halfway through, use break. Then, you can write

while True: # loop 'forever' until break
    grade = raw_input("enter grade ->")
    grade = int(grade)
    if grade == -1:
        break # we're done
    # rest of processing...
