I did not know about rjust and it can be very useful, thanks :) don't you prefer 'if else' insteaf of 'try except'? BTW: very nice this line "if 9 < num % 100 < 20:"

Yes, rjust often helps out. Try/except is not needed here at all. Thanks.

yess, many times I've tried to manage doing what you did with rjust in 3 more line ;)
