In Python object-oriented programming, the characteristics of multiple inheritance are as follows:

A subclass can inherit properties and methods from multiple parent classes. This means that a subclass can inherit different characteristics from multiple parents, increasing code reusability.
Multiple inheritance can lead to method duplication and naming conflicts. If multiple parent classes have the same method name, there may be ambiguity when the subclass calls this method, requiring the use of the super() function or specifying the method of the parent class to resolve it.
Python uses the C3 algorithm to determine the order of method calls in multiple inheritance. The C3 algorithm ensures that the method call order is consistent and follows the inheritance hierarchy in multiple inheritance scenarios.
Diamond inheritance problem: When a subclass inherits from two parent classes that have a common ancestor, the issue of diamond inheritance may arise. To address this problem, Python uses the C3 algorithm to determine the order in which methods are called.
Multiple inheritance can increase the complexity of the code. It may lead to method duplication and naming conflicts, ultimately raising the complexity and maintenance costs of the code. Therefore, careful design of class hierarchies is necessary when using multiple inheritance.
