What Are Class Methods and When To Use Them?
Class methods, as the name suggests, are bound to the class and not the instances of a class. They are especially useful for providing an alternative interface for creating instances.
Moreover, they can be also used to define utility functions that are related to the class rather than its instances.
For instance, one can define a class method that returns a list of all instances of the class. Another use could be to calculate a class-level statistic based on the instances.
To define a class method in Python, use the @𝐜𝐥𝐚𝐬𝐬𝐦𝐞𝐭𝐡𝐨𝐝 decorator. As a result, this method can be called directly using the name of the class.
