Multiple inheritance is a powerful feature that can enhance code reuse and organization, but it requires careful consideration of MRO (Method Resolution Order) to avoid potential conflicts or unexpected behavior.

In the case of exceptions, inheritance is mostly about creating an exception hierarchy. As you can see, ArithmeticError is a subclass of Exception. Internally, the differences between them are negligible. You can also see two of the subclasses of the OSError class, namely PermissionError and ...
Every object-oriented programming language must acquire some features like inheritance, use of class & objects, polymorphism, encapsulation, data abstraction. These features make the differentiation between a procedural and an object-oriented language. High-level languages like Java and Python allow...
that making another HTML template would mean repeating most of the HTML code you already wrote in theindex.htmltemplate. You can avoid unnecessary code repetition with the help of abase templatefile, which all of your HTML files will inherit from. SeeTemplate Inheritance in Jinjafor more ...
Design for inheritance when naming in Python. Do not use leading underscores. If a public name collides with a reserved keyword, then add a single trailing underscore to the name. For public data attributes, only name the attribute. If a class should be subclassed, name the attributes...
