What am I doing wrong here?

I see that this can be done in three lines of code. I guess i'll make get to the point where I can do this w/ my eyes closed in the fewest lines possible. But as of now, I don't see why this isn't working (even though not the most efficient way).

sillycase.py 
def sillycase(blueball):

    da_length = len(blueball)
    half_length = da_length / 2

    firstHalf = blueball[:half_length]
    secondHalf = blueball[half_length:]
    secondHalf = secondHalf.upper

    return int(firstHalf) + int(secondHalf)

You got pretty close, but there were four issues remaining:

  • half_length = da_length // 2   :point_left: "You'll want to use the int() function or integer division, //"
  • firstHalf = firstHalf.lower()   :point_left: (new line added) "the first half should be lowercased"
  • secondHalf = secondHalf.upper()   :point_left: method calls need parentheses after the name
  • return firstHalf + secondHalf   :point_left: keep the strings as strings (no "int" conversion)

Hi Joshua Howard,

It's a good effort, however there are a few things to consider:

  1. .upper() is a string method, you'll need the ()
  2. you might want to add a .lower() to your firstHalf as there is no guarantee it will be lowercase already
  3. you'll need to fix that return statement so it returns a string that is made up of firstHalf + lastHalf

I think you'll be fine to get it working now. Keep going, you're almost there!

Happy coding,
Dave.

Just one other thing ... reading your post again I note you state:

I see that this can be done in three lines of code

You could do it in a single return statement if you really wanted to but while that might be true it would mean bunching up a couple of method calls directly in the return statement. So yeah, a little less code, it's also a lot less readable.

Efficiency is obviously important, but so is readability and while there is room to improve in what you've got, don't be too hard on yourself :) That was a quality attempt you made there.

Also, do you really want to read a return line that looks like this (not meant to be efficient - 2x len calc - but ... single line):

return someWord[:(int(len(someWord)/2))].lower() + someWord[(int(len(someWord)/2)):].upper()
