Based on three scores that the user inputs, display the average of the score and the letter grade that is assigned fort he test

Korolek [52]

I used python function to write the code.

def averageScore(x,y,z):

s = x + y + z

avg = s/3

if avg >= 90:

return f'Your average test score is {avg} You earned a A.'

elif avg >=80 and avg < 90 :

return f'Your average test score is {avg} You earned a B.'

elif avg >=70 and avg < 80 :

return f'Your average test score is {avg} You earned a .C'

elif avg >=60 and avg < 70 :

return f'Your average test score is {avg} You earned a D.'

else:

return f'Your average test score is {avg} You earned a F.'

print(averageScore(98, 90, 80))

Python function is used to write the code where x, y and z are the argument (user inputs) of the function. Then the inputs are summed and the average is gotten and stored with the variable, avg.

If the average is greater than or equal to 90 the program will give the appropriate score and response(grade). It does the same if the user scored 80 - 89, 70 - 79, 60 - 69 and less than 60.

Finally. the function is called with the user input(argument).

Note the bolded values in the code are keywords in python.
