This is very useless, because helps to make a good and clean code without too many error to fix, like this example:<\/span><\/p>\n

while  True:<\/strong>
        try:<\/strong>
            q=int(input(“Please enter a non-negative integer number: “))<\/strong>
            break<\/strong>
        except ValueError:<\/strong>
            print(“this is not a integer number, try again: “)<\/strong><\/p>\n

 <\/p>\n

while q<0:<\/strong>
        try:<\/strong>
            q=int(input(“this is not a positive number,try again: “))<\/strong>
        except ValueError:<\/strong>
            print (“this is not a integer number, try again:  “)<\/strong>
            while True:<\/strong>
                try:<\/strong>
                    q=int(input(“Please enter a non-negative integer number: “))<\/strong>
                    break<\/strong>
                except ValueError:<\/strong>
                    print (“this is not a integer number, try again: “<\/strong>)<\/p>\n
