Name Prototype Pattern Type Creational Pattern; In this design pattern an existing object is copied to a new object.So we get a new object initialized with the state information from an existing object.The new object that is created using the Original object is different from the original object though it contains the same state information. 1.4.

The Prototype pattern specifies the kind of objects to create using a prototypical instance. Code example. Probably the most important step forward in object-oriented design is the “design patterns” movement, chronicled in Design Patterns (ibid).That book shows 23 different solutions to particular classes of problems. You can check out C#/Java implementation over here. Prototype design pattern is good for when creating new objects may require more resources than you want to use or have available, versus just making a new copy in memory. In the prototype pattern you create a new instance cloning from other. Overview This is the first article in a short series dedicated to Design Patterns in Python [/design-patterns-in-python].
