Gaah. Typos. My apologies. Here's a correction to double()
def double(s):
"""double: string -> string
Doubles up the input string s. For example, double("abc")
should return "abcabc".
"""
return s + s

I meant to say that the expected content of the file should be:
"hello worldhello world"
My apologies; I rushed that message too quickly.
