Do I wrong something?

I tested this code by using workspace, it worked but not in challenge.

sillycase.py 
def sillycase(string):
    string = 'treehouse'
    do_cased = string[:4]
    up_cased = string[4:]
    return do_cased.lower() + up_cased.upper()

If you move 

string = 'treehouse'

to the top, outside of your function, it should pass. Otherwise you get a NameError due to the string not already being defined. If not, let me know.
