Question

How can I modify my program to accept a list of integers (up to 20 entries) from the user into a list and prints the numbers entered by the user in ascending order, their sum and their average. The program then stops when the user inputs -100 as a number to search.

#function that returns largest number
def max(numOne,numTwo,numThree):
if(numOne > numTwo and numOne > numThree):
return numOne
elif(numTwo > numOne and numTwo > numThree):
return numTwo
elif(numThree > numOne and numThree > numTwo):
return numThree
#function that returns middle number
def mid(numOne,numTwo,numThree):
if(numOne < numTwo and numThree > numTwo):
return numTwo
elif(numOne < numThree and numTwo > numThree):
return numThree
elif(numTwo < numOne and numThree > numOne):
return numOne
elif(numTwo < numThree and numOne > numThree):
return numThree
elif(numThree < numOne and numTwo > numOne):
return numOne
elif(numThree < numTwo and numOne > numTwo):
return numTwo
#function that returns smallest number   
def min(numOne,numTwo,numThree):
if(numOne < numTwo and numOne < numThree):
return numOne
elif(numTwo < numOne and numTwo < numThree):
return numTwo
elif(numThree < numOne and numThree < numTwo):
return numThree
#function that calculates the sum   
def sum(numOne,numTwo,numThree):
sumOfThree = int(numOne + numTwo + numThree)
return sumOfThree
#function that calculates average   
def avg(numOne,numTwo,numThree):
average = ((numOne + numTwo + numThree)/3)
return average
#start of main
#prompts user for 3 numbers
numOne = int(input("Enter 1st number: "))
numTwo = int(input("Enter 2nd number: "))
numThree = int(input("Enter 3rd number: "))
print("You just entered 3 integers:", numOne, numTwo, numThree)
#loop that will exit and quit the program once the user enters -7 as their first number
while (numOne != -7):
#condition to print if all three numbers are equal
if(numOne == numTwo == numThree):
print ("These 3 integers in order are",numOne,numTwo,numThree)
else:
print ("These 3 integers in order are", min(numOne,numTwo,numThree),
mid(numOne,numTwo,numThree), max(numOne,numTwo,numThree))
print("Their sum is", sum(numOne,numTwo,numThree), "and their average is",
avg(numOne,numTwo,numThree))
numOne = int(input("\nEnter your 1st number: "))
numTwo = int(input("Enter your 2nd number: "))
numThree = int(input("Enter your 3rd number: "))
print("You just entered 3 integers:", numOne, numTwo, numThree)
#end of main

Answer 1

Here is code:

def printArray(array):

for i in array:

print(i," ",end=' ')

print()

#function that calculates the sum

def sum(array):

total = 0

for i in array:

total += i

return total

#function that calculates average

def avg(array):

return (sum(array)/len(array))

#start of main

data = []

while(True):

#prompts user for 3 numbers

num = int(input("Enter number (-100 to quit): "))

if(num == -100):

break

data.append(num)

if(len(data) == 20):

break

print("you have entered : ")

printArray(data)

data.sort()

print("ascending order : " )

printArray(data)

print("Their sum is", sum(data), "and their average is",

avg(data))

#end of main

Output:
