Question

Please add notes to the following #Python script to help the novice user communicate with the program:

s = input('Enter space separated integers: ')
lst = [int(x) for x in s.split(" ")]
avg = 0
if(len(lst)>2):
lst.sort()
for x in lst[2:]:
avg += x
avg = avg / (len(lst)-2)
print("Average =",avg)

Answer 1

#Reading a line of string from user 
s = input('Enter space separated integers: ')

#splitting the string based on space and converting the each splitted value to integer using int()
lst = [int(x) for x in s.split(" ")]

#Defining avg and assigning 0 to it
avg = 0

#Checking that user enters more than 2 numbers
if(len(lst)>2):
    #Sorting the numbefrs entered by user
    lst.sort()
    #lst[2:] trims the first 2 values in the list
    #This means removing 2 least enties in the list
    for x in lst[2:]:
        #Calculating sum
        avg += x
    #Calculating average using sum
    avg = avg / (len(lst)-2)
    #printing avg
    print("Average =",avg)
