I have also added print (type (x)) to verify that that x is integer , however I am getting an error Bummer! slice indices must be integers or None or have an index method"
# The first half of the string, rounded with round(), should be lowercased.
# The second half should be uppercased.
# E.g. "Treehouse" should come back as "treeHOUSE"
def sillycase(justastring = 'Treehouse'):
x = len(justastring) / 2
print (type(x))
return (justastring[:x].lower() + justastring[x :].upper())

is a float. Correct this by using the round()
function to get the nearest integer:
x = round(len(justastring) / 2)

3,313 Pointsactually when I use round (x) i get the following error from python interpreter "TypeError: slice indices must be integers or None or have an index method" and its type changes to float . I am python 2.7.10. I don't mind casting to int , but it is pointless, hence its integer from the start
x = int(round(len(justastring) / 2))
anyway for some reason the line I just typed above worked , would love to hear explanation why .

Treehouse Moderator 68,457 PointsThe challenges run in Python 3, but I see your error when running Python 2:
To bulletproof the code for both Python 2 and 3 add an extra cast to int
