Write a Python program to add 'ded' at the end of a given word (length should be at least 3). If the given string already ends with 'ded' then add 'ing' instead. If the string length of the given string is less than 3, leave it unchanged.

For example if the word is Hello your print out should say Helloded

If your word is graded, your print should say gradeding.

If your word is at, it should print at

Hint use an if statement, but again that is not the only way to answer this question.

Can you please do it by python idle 3.5

thank you
