Programming for everybody (Python) Assignment 5.2

Coursera: Programming for everybody with Python 
Assignment 5.2
Week 7
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.

Solution:-
largest = None
smallest = None
while True:
 try:
  num = input("Enter a number: ")
  if num == "done":
   break
  #print (num)
  num = int(num)
  if largest is None or largest < num:
   largest = num

  •   elif smallest is None or smallest > num:

   smallest = num
 except ValueError:
  print("Invalid input")

print ("Maximum is", largest)
print ("Minimum is", smallest)
