Question

Write a program that requests some grades as inputs, and displays the average after dropping the smallest and the largest grades! Your program should stop asking the user for a new grade when the user typed any negative number.

Here is a sample run:

Enter a grade?40

Enter a grade?50

Enter a grade?60

Enter a grade?70

Enter a grade?80

Enter a grade?90

Enter a grade?100

Enter a grade?-1

70.0

Note that in this example 40 is the lowest grade and 100 is the largest grade, and therefore are dropped, then the average is (50+60+70+80+90)/5=70.

Do this in python

Answer 1

The code is given below-

lst=[]
count=0
n=int(input("Enter a grade?"))
if(n>=0):
    while(n>=0):
        lst.append(n)    #entering the values in the list
        count=count+1     #counting the number of elements
        n=int(input("Enter a grade?"))
    max_value=max(lst)   #finding max value from list
    min_value=min(lst)    #finding min values
    #print(max_value)
    count=count-2     #removing count for max and min value
    sum_value=0
    lst.remove(max_value)   #removing max value
    lst.remove(min_value)   #removing min value
    if(count>0):
        for i in lst:
               # print(i)
                sum_value=sum_value+i   #summing up the values 
        avg=sum_value/count    #calculating average
        print(avg)
    else:
        print('0')
