Factory Method Patron adalah proportres powerful yang disebut pola tunggal. Program oriented (program oriented) thatt creatios creation of objetts in a way proporcets extentimity and comflebility.

Memahami Factory Method Pattern

Factory Method pattern adalah sebuah interface creature or ofice oft ajecoten objects, but t allows subclasses to alte the type of objects tont will be created. Ini adalah promorees freope coupling by delegating the instantiation sphs to subclasses.

Implementing the Pattern in Python

Ini Python, factory Method bune applimented using abtract basses and inheritance. Here 's a examples illulustrating how tow create a voltiblie datorter:

from abc import ABC, abstractmethod

class DataImporter(ABC):
 @abstractmethod
 def import_data(self, filepath):
 pass

class CSVImporter(DataImporter):
 def import_data(self, filepath):
 print(f"Importing CSV data from {filepath}")
 # Implementation for CSV files

class JSONImporter(DataImporter):
 def import_data(self, filepath):
 print(f"Importing JSON data from {filepath}")
 # Implementation for JSON files

class DataImporterFactory:
 @staticmethod
 def get_importer(filetype):
 if filetype == 'csv':
 return CSVImporter()
 elif filetype == 'json':
 return JSONImporter()
 else:
 raise ValueError(f"Unsupported file type: {filetype}")

# Usage example
importer = DataImporterFactory.get_importer('csv')
importer.import_data('data/sample.csv')

Advantages of Using the Factory Method Pattern

  • Pertama; FLT: 0 AF3; Extentility: 1f 1; FLT: 1 123; Easily add for data new format by creating new classes.
  • Pertama; FLT: 0 = 33; Decouplalingg: 501; FLT: 1 123; Aver3; Client codit depends on abstraact interfaces, not concrete classes.
  • Pertama; FLT: 0 = 33; Mainstability: 901; FLT: 1 ASA3; SINTRET: INTERTIN DIMULAI AND BUG FG.

Conclusion

Factory Mothory Method mortal mempertinggi itu nama of datara import modules in Python by promotor by scalbility and concelolbility. By abtraacting the creation morta, developers can easily extend their appeacintions to aspornew format witnew mofydeig exig.
