A decoration @dec... def f(...): ... is a shorthand notation for def f(...): ... f = dec...(f) In your first example, "fahrenheit" is defined as you expect. In the second example, some property functions are bound to `f`. It depends on implementation details, whether the final `f` and/or `fahrenheit` has both getter/setter definitions. Always use the same name for function and property (as you do in your first class). -- https://mail.python.org/mailman/listinfo/python-list
