the problem your having is that first you need to get the middle point of the string. so lets say you had the word "love" the middle point would be the "o". but what happens if you had "loves"? the middle would be 2.5 right? since theres 5 letters. thats why you need to round the middle point. so that part would look like this

def sillycase(str):
  length = round(len(str)/2)

btw i just write str because it can be any string of type str.

then the part that deals with the return. 

  return str[:length].lower() + str[length:].upper()

we are slicing the string that we passed. starting at the beginning and ending at the length. remember that length holds the middle point of the string. then we are just using the method .lower() to make it lower case. then we concatenate it to the second part of the string which would start at the length and go to the end [length:] and then we make that upper case. and thats the solution. hope that helped

I would caution against using "str" as a function parameter or local variable name since it is the name of the built-in class str(). Using "string" is acceptable.
