In python, explanations help, Thanks!

3. Implement the function printTwoLargest0 that inputs an arbitrary number of positive numbers from the user. The input of numbers stops when the first negative or zero value is entered by the user. The function then prints the two largest values entered by the user. If fewer than two distinct positive numbers are entered a message to that effect is printed instead of printing any numbers. If the user enters something other than a number, the program should display an error message and then continue with the entry of values. This will involve exception handling. Hint: Duplicates will cause problems. Try to make sure that you find a way to ignore them. The information below shows how you would call the function and what it would display for several sample runs
