silly.py

Not sure how to proceed

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(string):
  string_length = len(string)
  half_string = string_length / 2
  first_half = string[:half_string]
  result = first_half.extend(string[half_string:])
  return result

You are very close. A few corrections to you code. extend() works on lists but not on strings. 

def sillycase(string):
  string_length = len(string)
  # need to round when length is odd
  half_string = round(string_length / 2)
  first_half = string[:half_string]
  # lower first half and upper second half 
  result = first_half.lower() + string[half_string:].upper()
  return result

Thanks Chris! After struggling through splitting up the first_half and second_half I totally forgot to .lower() the first half and .upper() the second half. Haha

I was also wondering about issues that would arise from input(string) with an odd number of elements. So, "round()" will takes care of this?

Yes. By default round() rounds to the nearest integer. 3.5 becomes 4, etc.
