Python Python Collections (2016, retired 2019) Slices sillyCase

Excercise solution saying “not finding the correct output”

Hi Treehouse,

My code (attached) in the exercise brings the error that it’s not producing the correct output. However when I test it in Pythonista, it works fine. If ‘treehouse’ is the input the output is ‘treeHOUSE’.

sillycase.py
def sillycase(thing):
    half = len(thing) / 2

    new_1 = thing[int(half):]
    new_2 = thing[:int(half)]

    new = new_2 + new_1.upper()

    return new

You need to make sure that all of the letters in the first half are lowercased as well. sillycase('Treehouse') should return treeHOUSE, but with you code it returns TreeHOUSE. Fix that and you'll be good to go :)

Ah okay! I didn’t know that was a criteria, thank you!

My pleasure! Happy coding :)
