what is the problem with the code?

def sillycase(a): x=a[:index(len(a)/2)].lower() y=a[index(len(a)/2):].upper() z=x+y return z

silly.py 
# 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(a):
    x=a[:index(len(a)/2)].lower()
    y=a[index(len(a)/2):].upper()
    z=x+y
    return z

Hi Selcuk,

I had trouble with this one a few days ago as well. I found that the issue was we have to use the round function when are dividing the length of the string to avoid getting floats. Also, you don't need to create variables for this function- you can simply concatenate the two strings. Hope this helps and happy coding! :)

def sillycase(string):
    return string[:round(len(string)/2)].lower() + string[round(len(string)/2):].upper()
