I don't know. The answer is likely to be dependent on many details of the code and the data. But I do know that the different operators communicate different intents. And that should be a primary reason for choosing which operator to use: communicate your intent to the reader of the code. > My use-case scenario are matplotlib objects, the __eq__ operator might > involve a bit of work. Then IMO you should choose the operator which matches your intent, and stop worrying about “efficient” until you have measured exactly which part of the code is slow. It sounds like you are interested in value equality. So you should use ‘==’ for this purpose. -- \ “A free press is one where it's okay to state the conclusion | `\ you're led to by the evidence.” —Bill Moyers | _o__) | Ben Finney -- https://mail.python.org/mailman/listinfo/python-list
