What is Class Variable In Python?
A class variable in Python is a variable that is shared among all instances of a class. Unlike instance variables, which are unique to each object, class variables are defined within the class itself and can be accessed using the class name or through instances of the class. They are typically used for properties that should have the same value across all instances, such as constants or default settings. Class variables can be modified, but changes will affect all instances unless overridden by an instance variable with the same name. This feature promotes data consistency and efficient memory usage.
