Sometimes, the users of your program do not input exactly what you expect. Perhaps you ask them to put in a positive number, but they may input a negative number on accident. Worst case scenario: this breaks your program!
Write a program called `positivenumber.py` that uses a while loop to repeatedly ask the user to enter a positive number and says “Thanks!” once they did and “Oops! Try again.” if they did not.

Oops! Try again.
Please enter a positive number: 0
Oops! Try again.
Please enter a positive number: 4
Thanks!
