Private variables are enforced in Python only by convention. Names can also be suffixed with an underscore to prevent conflict with Python keywords. Prefixing with double underscores changes behaviour in classes with regard to name mangling. Prefixing and suffixing with double underscores - the so-called "dunder" ("double under") methods in ...
Instead the class browser allows to edit the class together with its metaclass at the same time. The names of classes in the metaclass hierarchy are easily confused with the concepts of the same name. For instance: Object is the base class that provides common methods for all objects; "an object" is an integer, or a widget, or a Car, etc.
In Python, everything is an object, even classes. Classes, as objects, have a class, which is known as their metaclass. Python also supports multiple inheritance and mixins. The language supports extensive introspection of types and classes. Types can be read and compared—types are instances of type. The attributes of an object can be ...
In object-oriented programming, a class is a template that defines the state and behavior common to objects of a certain kind. A class can be defined in terms of other classes. [1] The concept of class hierarchy in computer science is very similar to taxonomy, the classifications of species.
Identifier names may be prefixed by an at sign (@), but this is insignificant; @name is the same identifier as name. Microsoft has published naming conventions for identifiers in C#, which recommends the use of PascalCase for the names of types and most type members, and camelCase for variables and for private or internal fields.

C# makes use of reification to provide "first-class" generic objects that can be used like any other class, with code generation performed at class-load time. [29] Furthermore, C# has added several major features to accommodate functional-style programming, culminating in the LINQ extensions released with C# 3.0 and its supporting framework of ...
Classes can be derived from one or more existing classes, thereby establishing a hierarchical relationship between the derived-from classes (base classes, parent classes or superclasses) and the derived class (child class or subclass) . The relationship of the derived class to the derived-from classes is commonly known as an is-a relationship. [21]
In class-based programming, inheritance is done by defining new classes as extensions of existing classes: the existing class is the parent class and the new class is the child class. If a child class has only one parent class, this is known as single inheritance , while if a child class can have more than one parent class, this is known as ...
