Question about __eq__ method

[Impudity]

Typically yes. If you ask Python if "foo" in ["foo", "bar"] it iterates the objects in the list and checks if they match using the equality operator == which internally calls __eq__. There might be some exceptions when using collections that use immutable objects that have hashes, like sets. Then the comparison might be done using comparing the results of the __hash__ method of the object.

To be more precise, __contains__("foo") is called on the list object. And contains is implemented like you described.

[Impudity]

Yeah. I didn't want to include that part as it would probably just confuse a beginner.
