does the order when defining functions in classes in python matter

Question

When defining variables and functions within a class in python 3.x does it matter in which order you define variables and functions?

Is class code pre-complied before you would call the class in main?

Answer 1

By default, all names defined in the block of code right within the class statement become keys in a dict (that's passed to the metaclass to actually instantiate the class when said block is all done). In Python 3 you can change that (the metaclass can tell Python to use another mapping, such as an OrderedDict, if it needs to make definition order significant), but that's not the default.
