Can't make it work on my pc

I've already passed this section but when I try to run this code on my computer I get an invalid syntax error.

I use the print command after the function. Eg: print sillycase('hello')

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(t):
  leng = round(len(t)/2)
  return t[:leng].lower() + t[leng:].upper()

len(t) / 2 will already preform integer division leaving you will a whole number. By adding the round(len(t) / 2) you are actually assigning 2.0 to leng and floating points numbers cannot be used for the string slicing operation. Remove round() and your program will work! 

def sillycase(t):
  leng = len(t)/2
  return t[:leng].lower() + t[leng:].upper()

print sillycase("hello")

Hope this helps!

print sillycase("hello")  #not correct
print(sillycase("hello")) #correct for Python 3.x

I guess I should have first asked what version of Python you are using?
