Knowledge
Advanced concepts in Python's object-oriented programming were explored, focusing on multiple inheritance, method resolution order, and the use of abstract base classes. Additionally, the chapter highlighted the differences between class methods and static methods, alongside how property decorators manage attribute access. Finally, the significance of data classes, named tuples, mixins, and favoring composition over inheritance for flexible designs were discussed.

What we have learnt
- Multiple inheritance allows a class to inherit from multiple parent classes.
- Method Resolution Order (MRO) resolves the ambiguity in method calls when using multiple inheritance.
- Abstract Base Classes (ABCs) provide a way to enforce method implementations in derived classes.
Key Concepts
-
Term: Multiple Inheritance
Definition: The ability of a class to inherit from more than one parent class, allowing for flexible design.
-
Term: Method Resolution Order (MRO)
Definition: The order in which Python searches for a method in the hierarchy of a class.
-
Term: Abstract Base Classes (ABCs)
Definition: Classes that cannot be instantiated and require subclasses to implement abstract methods.
-
Term: Class Methods
Definition: Methods that receive the class itself as the first argument, typically used for factory methods.
-
Term: Static Methods
Definition: Methods that do not require access to class or instance variables and are defined in a class's namespace.
-
Term: Property Decorators
Definition: Tools that define getter, setter, and deleter functions to manage access to instance attributes.
-
Term: Data Classes
Definition: Classes primarily used to store data with less boilerplate code, introduced in Python 3.7.
-
Term: Mixins
Definition: Small classes that provide specific functionality to other classes through multiple inheritance.
-
Term: Composition over Inheritance
Definition: Design principle that favors using composition (has-a relationship) instead of inheritance (is-a relationship) for code flexibility.
