The Idea is to show how to deal with a few classes, their attributes, methods (including __dunder__ methods.) and some inheritance. I feel that the cards example is very ilustrative and intuitive. Besides, printing the cards on the little boxes is very cool for the first week of class...
In this comparison, I will try to cover some basic language components, such as string, control flow, class, inheritance, file i/o, etc. All of them will be compared by using side-by-side examples. I hope this can provide java programmers a general idea of how Python and Java do the...
// C++ program to demonstrate example of // private simple inheritance #include <iostream> using namespace std; class A { private: int a; protected: int x; // Can access by the derived class public: void setVal(int v) { x = v; } }; class B : private A { public...
Python’s standard method resolution order (MRO) solves the problems of superclass initialization order and diamond inheritance; Always use the super built-in function to initialize parent classes. Item 26: Use Multiple Inheritance Only for Mix-in Utility Classes ...
The main motivation is to allow modeling the database directly in SQL, taking full advantage of the capabilities offered by the PostgreSQL engine (triggers, views, functions, stored procedures, inheritance handling...), while avoiding the "impedance mismatch" issues, loss of control over generated...

For the sake of brevity we define theAST.__repr__method asself.__str__and leaveAST.__str__undefined; then for eachASTNodesubclass we only have to define the magic method__str__as we get the__repr__for free with inheritance.
