Grade Loop

[dtweaponx]

Hello, my assignment is to make a program that allows a teacher to enter any number of tests grades and it will give them the average. My problem is my average isn't correctly working? For example I plug in numbers 85, 75, 96 I SHOULD get 85.3. However I'm getting in my return, 86.2. Anyone able to tell me where my math is wrong or what would be causing this to spit out a number 1.1 off?

My code:

count = 0
total = 0
toContinue = "y"
while toContinue != "n":
    grade = int(input("Enter a test grade: "))
    for eachPass in range(grade):
        count = count + 1
        total = total + grade
    toContinue = input ("Are there any more test grades to enter, 'y' or 'n'? ")
    if toContinue == "n":
        print("The average is", round(total / count, 1))
        print("I'm done")
        break

Run this
 

count = 0
total = 0
toContinue = "y"
while toContinue != "n":
    grade = int(input("Enter a test grade: "))
    for eachPass in range(grade):
        count = count + 1
        total = total + grade
        print('eachPass: {}, total: {}'.format(eachPass, total))
    toContinue = input ("Are there any more test grades to enter, 'y' or 'n'? ")
    if toContinue == "n":
        print('Final total: {}, Final count: {}'.format(total, count))
        print("The average is", round(total / count, 1))
        print("I'm done")
        break

Does it make more sense now, why you get incorrect average? :-)

I'm a total noob here to python (taking classes on it), would you care to explain just a tiny bit more?

did you run it? I just added 2 print functions to show you what is going on in your code.

Yeah, the grade number is multiplying its self. So, should I change the "range"?

[buran]

you should ask yourself 'Do I need that range loop?'

:D I see what I did there. I got it working. Thanks!!!

Please, don't PM. If you removed the loop (line#6) and unindent lines#7 and#8 one level your code should work

If you fix it - why don't you refactor your code(i.e. change it) to avoid asking user each time is there another grade... This will make user experience much better
