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.

A program that repeatedly prompts a user for integer numbers :

biggest = none

smallest = none

while True:

input = raw_input(“Enter a number:”)

if(input == “done” break

try:

 number = float(inp)

 except ValueError:

 print “Please enter only numbers”

else

 if smallest is None:

 smallest = number;

 biggest = number;

elif number < smallest:

 smallest = number

elif num > largest:

 largest = number

Print “Greatest is “, biggest

Print “Smallest is”, smallest

In this program an input is obtained, if it is equal to the word “done”, then the program stops b printing greatest and smallest number in the given input.

If invalid inputs are given then user is prompted to enter valid number. Otherwise the value of smallest and greatest are calculated according to the input using if-else construct.
