How to overload operators like and * for custom Python classes?
Article Introduction：To overload the sum and equal operators in Python, you need to define the corresponding special methods in the class: 1. Use the __add__ to implement the operator, and use the __add__ method to make the custom object support addition operations, such as implementing the addition of two vectors in the Vector class; 2. Use __mul__ and __rmul__ to implement the operator, __mul__ to handle the left multiplication, and __rmul__ to handle the right multiplication to ensure that the scalar multiplication can work normally on both sides of the left and right; 3. The corresponding methods of common operators include __sub__, __truediv__, __eq__, __lt__, etc., which support subtraction, division, equality, less than, etc.; 4. Best practices include checking other types and returning

What are Python magic methods or dunder methods?
Article Introduction：Python's magicmethods (or dunder methods) are special methods used to define the behavior of objects, which start and end with a double underscore. 1. They enable objects to respond to built-in operations, such as addition, comparison, string representation, etc.; 2. Common use cases include object initialization and representation (__init__, __repr__, __str__), arithmetic operations (__add__, __sub__, __mul__) and comparison operations (__eq__, ___lt__); 3. When using it, make sure that their behavior meets expectations. For example, __repr__ should return expressions of refactorable objects, and arithmetic methods should return new instances; 4. Overuse or confusing things should be avoided.

How to implement operator overloading in Python (e.g., __add__, __sub__)?
Article Introduction：How to effectively implement operator overloading in Python? 1. Specify operator behavior by defining special methods (such as __add__, __sub__) in the class. For example, in the Vector class, use __add__ to implement vector addition and return a new instance; 2. To support the situation where the object is on the right side of the operation, it is necessary to define methods such as __radd__, __rsub__, etc.; 3. Other common operators such as __mul__, __eq__, __lt__, etc. can be overloaded to extend functions; 4. Pay attention to handling type checks and return value consistency to ensure interaction reliability.
