Pythonic way of adding "ly" to end of string if it ends in "ing"?
<p>This is my first effort on solving the exercise. I gotta say, I'm kind of liking Python. :D</p>

<pre><code># D. verbing
# Given a string, if its length is at least 3,
# add 'ing' to its end.
# Unless it already ends in 'ing', in which case
# add 'ly' instead.
# If the string length is less than 3, leave it unchanged.
# Return the resulting string.
def verbing(s):
  if len(s) &gt;= 3:
    if s[-3:] == "ing":
      s += "ly"
    else:
      s += "ing"
    return s
  else:
    return s 

  # +++your code here+++
  return
</code></pre>

<p>What do you think I could improve on here? </p>
