problem with function return value

[snippsat]

You are missing basic understanding how class works.
So read more about it.

I dont know what the function anything will return

It's not called a function when it belong to class,it's now a method.
You should not have variables outside the class,
these should be arguments that is given to the class.
Just to write something that make more sense,in the way class work.
Not changing anything to method anything which could be wrong.

class xyz:
    def anything(self, anything, somethingelse, a):
        if something < somethingelse:
            if a == 10:
                return something
            else:
                return somethingelse
        elif a > somethingelse:
            return something
        else:
            return something

    def calculations(self, any_obj):
        x = any_obj + 5
        y = any_obj + 10
        return x, y

object1 = xyz()
something = 10
somethingelse = 0
a = 2
any_obj = object1.anything(something, somethingelse, a)
print(object1.calculations(any_obj)) #(15, 20)
