Python supports multiple inheritance, allowing a class to inherit from more than one parent class. This means a child class can inherit attributes and methods from multiple base classes. Python handles multiple inheritance using the Method Resolution Order (MRO), which determines the sequence in which methods are searched for in a class hierarchy. The C3 linearization (or MRO algorithm) ensures a predictable and consistent order when resolving methods, preventing conflicts and redundant calls.
To implement multiple inheritance, a class simply lists multiple parent classes in its definition. For example, class Child(Parent1, Parent2): allows Child to inherit from both Parent1 and Parent2. If the same method exists in multiple parent classes, Python follows the MRO, which can be checked using ClassName.__mro__ or help(ClassName). The super() function also plays a role in managing inheritance, ensuring that each parent class is initialized properly without redundant calls. While multiple inheritance is powerful, it should be used carefully to avoid complexity and method conflicts in large-scale applications.
