  2. Scope (computer science) - Wikipedia

    en.wikipedia.org/wiki/Scope_(computer_science)

    A fundamental distinction in scope is what "part of a program" means. In languages with lexical scope (also called static scope), name resolution depends on the location in the source code and the lexical context (also called static context), which is defined by where the named variable or function is defined.

  3. Python syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/Python_syntax_and_semantics

    Python allows the creation of class methods and static methods via the use of the @classmethod and @staticmethod decorators. The first argument to a class method is the class object instead of the self-reference to the instance. A static method has no special first argument. Neither the instance, nor the class object is passed to a static method.

  5. Local variable - Wikipedia

    en.wikipedia.org/wiki/Local_variable

    Local variables may have a lexical or dynamic scope, though lexical (static) scoping is far more common.In lexical scoping (or lexical scope; also called static scoping or static scope), if a variable name's scope is a certain block, then its scope is the program text of the block definition: within that block's text, the variable name exists, and is bound to the variable's value, but outside ...

  6. Closure (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Closure_(computer_programming)

    The scope of the variable encompasses only the closed-over function, so it cannot be accessed from other program code. These are analogous to private variables in object-oriented programming , and in fact closures are similar to stateful function objects (or functors) with a single call-operator method.

  7. Name binding - Wikipedia

    en.wikipedia.org/wiki/Name_binding

    Dynamic binding (or late binding or virtual binding) is name binding performed as the program is running. [2] An example of a static binding is a direct C function call: the function referenced by the identifier cannot change at runtime. An example of dynamic binding is dynamic dispatch, as in a C++ virtual method call.

  8. Variable (computer science) - Wikipedia

    en.wikipedia.org/wiki/Variable_(computer_science)

    Scope is an important part of the name resolution of a variable. Most languages define a specific scope for each variable (as well as any other named entity), which may differ within a given program. The scope of a variable is the portion of the program's text for which the variable's name has meaning and for which the variable is said to be ...

  9. Late binding - Wikipedia

    en.wikipedia.org/wiki/Late_binding

    The name dynamic binding is sometimes used, [2] but is more commonly used to refer to dynamic scope. With early binding, or static binding, in an object-oriented language, the compilation phase fixes all types of variables and expressions. This is usually stored in the compiled program as an offset in a virtual method table ("v-table"). [3]
