Sorry if I am missing something. But. what is sorted here?
My simplified function looks like this
def myFunction( myNumber ):
"do some math calculations to myNumber"
return "result of calculations"
So, I want to sort myList by the return of myFunction( value3 )
I tried doing the following... with no luck so far
myList.sort(lambda x, y: cmp(myFunction(x[2]), myFunction(y[2]))
Thanks for any help.
