Better way of completing sillycase challenge

Question

Challenge:
This one will be named sillycase and it'll take a single string as an argument.
sillycase should return the same string but the first half should be lowercased and the second half should be uppercased.
For example, with the string "Treehouse", sillycase would return "treeHOUSE".
def sillycase(string):
    half = int(len(string) /2 )
    newlist = []
    for x in list(string)[:half]:
        x = x.lower()
        newlist.append(x)
    for x in list(string)[half:]:
        x = x.upper()
        newlist.append(x)
    string = ''.join(newlist)
    print(string)
    return string
sillycase("hello")
sillycase("treehoure")
I got the right answer i'm just wondering if there was a better way

Here's a few ways to optimize the function:
- you can use string concatenation to join strings directly instead of using a list as an intermediate
- you could also apply the case conversions directly to the slices and save a few more steps
- and the function doesn't need to "print" anything
