Memahami bahwa Fakultas Abtractt Pattern

Ini adalah satu-satunya cara untuk mengubah apa yang kita inginkan.

Implementing the Pattern in Python

Ini Python, menerapkan bahwa Factory Abtractory tidak sengaja menjelaskan interface obstracts for for products dan facts, mereka creatine concrete kelas itu menerapkan interface. Ini acquits promoth loope couplingg and meningkatkan skability.

Defining Abstract Interfaces

Mulai by defining abstraact classes or interfacks for your products and factores. Python 's lep1; FLT: 0: 3; Module helples the se interfaces.

from abc import ABC, abstractmethod

class Button(ABC):
 @abstractmethod
 def render(self):
 pass

class Checkbox(ABC):
 @abstractmethod
 def render(self):
 pass

class GUIFactory(ABC):
 @abstractmethod
 def create_button(self):
 pass

 @abstractmethod
 def create_checkbox(self):
 pass

Creatinger Concrete Factorees and Products

Next, implementt concrete classes for each product familiy and factory. For exiple, Windows and Mac themes can be diferen t product families.

class WindowsButton(Button):
 def render(self):
 print("Render a Windows style button.")

class WindowsCheckbox(Checkbox):
 def render(self):
 print("Render a Windows style checkbox.")

class WindowsFactory(GUIFactory):
 def create_button(self):
 return WindowsButton()

 def create_checkbox(self):
 return WindowsCheckbox()

class MacButton(Button):
 def render(self):
 print("Render a Mac style button.")

class MacCheckbox(Checkbox):
 def render(self):
 print("Render a Mac style checkbox.")

class MacFactory(GUIFactory):
 def create_button(self):
 return MacButton()

 def create_checkbox(self):
 return MacCheckbox()
