Hi J.J.,

It looks like a font problem between epub and Wing. I copied and pasted your code and it had syntax errors for me. I also tried copying and pasting from the PDF version, and that one actually worked. Here’s what I have in

def to_celsius(t):
    return (t - 32.) * 5 / 9

def above_freezing(t):
    return t > 0

And here is my shell interaction:

>>> import temperature
>>> temperature.above_freezing(temperature.to_celsius(33.3))

My guess for what caused your problem is that, because there was a syntax error in your file, the functions weren’t getting properly define.
