Out of all these, the most important one is __eq__, which is used to compare objects for equality.
__and__: The bitwise AND method. It is called when the&operator is used on an object.__or__: The bitwise OR method. It is called when the|operator is used on an object.__xor__: The bitwise XOR method. It is called when the^operator is used on an object.__lshift__: The left shift method. It is called when the<<operator is used on an object. (It is rarely used.)__rshift__: The right shift method. It is called when the>>operator is used on an object. (It is rarely used.)__lt__: The less than method. It is called when the<operator is used on an object.__le__: The less than or equal to method. It is called when the<=operator is used on an object.__eq__: The equal to method. It is called when the ’==’ operator is used on an object. Be careful when overriding this method, it can lead to unexpected results when comparing objects for equality, especially in a large codebase where the object implementing it is the main business component and it is used in many places.__ne__: The not equal to method. It is called when the!=operator is used on an object.__gt__: The greater than method. It is called when the>operator is used on an object.__ge__: The greater than or equal to method. It is called when the>=operator is used on an object.
