Is there an equivalent of Javascript's hasOwnProperty() in Python?

Question

I want to check whether an object has an attribute as a direct (ie not inherited) property, similar to Javascript's obj.hasOwnProperty() . How can I do this in Python? hasattr() seems to return inherited attributes as well.

Answer 1

Have you tried using "in"?

If you have a class object you can check if an attribute was defined by:

"what_you_want_to_search" in object.__dict__

Answer 2

In python you can try using if/in. eg obj = {"a": 1, "b":2, "c":3}

if "a" in obj: your code.
