sillycase challenge: what's wrong with my solution?

Ok, so I tried to follow each step methodically, when I get to the return portion it throws error:

Bummer! unsupported operand type(s) for +: 'builtin_function_or_method' and 'builtin_function_or_method'

Do I have to convert the strings to a list first and then join them?

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(str):
  half = round(len(str) / 2)  
  first = str[:half]
  last = str[half:]
  return first.lower + last.upper
#sillycase('Kenneth')

Since lower and upper are methods, you'll want to add parentheses at the end to call them:

return first.lower() + last.upper()

This will add what the methods return rather than attempt to add the methods themselves together.

Yep, it was the parenthesis. Can't believe I forgot them. I guess I made a 'silly' mistake... j/k

Thanks Dan!
