You're missing the () off the whole=file.read() call.
Ask youself, what is "file.read"? It is of course a method of the "file"
object. And, in fact that's exactly what Python itself is telling you also.
So when you say:
whole=file.read
You're assigning the method itself, to the name "whole". Consequently, you
would be able to do:
something = whole()
... which would then *call* the function using the name "whole", which would
be identical to calling that same function via "file.read".
To reiterate, there's a difference between just referencing a method or
function and actually calling it. To call it you need to use parentheses.
