Question

5.2 Write a program that repeatedly prompts a user for integer numbers until the user enters 'done'. Once 'done' is entered, print out the largest and smallest of the numbers. If the user enters anything other than a valid number catch it with a try/except and put out an appropriate message and ignore the number. Enter 7, 2, bob, 10, and 4 and match the output below. ​ 1 largest = None 2 smallest = None 3 while True: 4 num = input("Enter a number: ") 5 if num == "done" : break 6 print(num) 7 8 print("Maximum", largest)

Answer 1

maxVal = None
minVal = None
while(True):
    num = input("Enter a number: ")
    if num == "done":
        break
    try:
        val = int(num)
        if(maxVal == None):
            maxVal = val
        if(minVal == None):
            minVal = val
        if(maxVal < val):
            maxVal = val
        if(minVal > val):
            minVal = val
    except Exception as e:
        print("Error: Please enter only valid integers")
print("Maximum:",maxVal)
print("Minimum:",minVal)

Output:

Enter a number: 7 Enter a number: 2 Enter a number: bob Error: Please enter only valid integers Enter a number: 10 Enter a number: 4 Enter a number: done Maximum: 10 Minimum:2 Process finished with exit code 0
