Can't seem to pass this challenge

I'm having difficulty with this challenge.

I guess my question is how do you determine the first and second half.

Also do I need a for loop for this question

silly.py 
def sillycase(str):
    num=int(len(str)/2)
    return str[:num].lower()

# 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"

First, you have a good start with lowercasing the first part of the string. You just have to uppercase the second half in a similar fashion and concatenate the two halves back together.

Second, the comments suggest which function you should use to deal with fractions (ie. odd-length strings) which behaves slightly different than int()

Third,str is a built-in function in Python for the string type. You should see that the code window highlights it in the same color as other keywords like def and return. It can't be used as a variable name so you'll need to pick a new one.
