class variables (also called static member variables), where only one copy of the variable is shared with all instances of the class; and instance variables...

class variable is a variable defined in a class of which a single copy exists, regardless of how many instances of the class exist. A class variable is not...

For instance, a variable might be referenced by the identifier "total_count" and the variable can contain the number 1956. If the same variable is referenced...

Python by using a publicly exposed instance variable, and later changes the implementation to use a private instance variable exposed through a property descriptor...

to hold all the instance variables for an object, sets all the instance variables to zero values, and turns the memory into an instance of the class; at...

by all. The two kinds of variables commonly used in Smalltalk are instance variables and temporary variables. Other variables and related terminology depend...

A random variable (also called random quantity, aleatory variable, or stochastic variable) is a mathematical formalization of a quantity or object which...

A variable is considered dependent if it depends on an independent variable. Dependent variables are studied under the supposition or demand that they...

arguments that the constructor uses to set required member variables. A constructor resembles an instance method, but it differs from a method in that it has...

calculation of the sum of normally distributed random variables is an instance of the arithmetic of random variables. This is not to be confused with the sum of...

object has its own version of these variables. Member variables – refers to both the class and instance variables that are defined by a particular class...

dependent variables, Pressure, and Volume, can quickly be established by changing the value for one or the other, and this is Boyle's law. For instance, if...

A metasyntactic variable is a specific word or set of words identified as a placeholder in computer science and specifically computer programming. These...
