Series.str can be used to access the values of the series as strings and apply several methods to it. Creational Patterns These design patterns provide a way to create objects while hiding the creation logic, rather than instantiating objects directly using new operator. Facade pattern hides the complexities of the system and provides an interface to the client using which the client can access the system. Python . In Factory pattern, we create object without exposing the creation logic to the client and refer to newly created object using a common interface. This type of design pattern comes under creational pattern as this pattern provides one of the best ways to create an object.
