標籤：如何   dict   python   函數   屬性   object   __weak   pre   code   

1、如何使用類

# 先定義類class LuffyStudent():    school = "luffycity"  # 資料屬性    def learn(self):  # 函數屬性        print("is learning...")    def sleep(self):  # 函數屬性        print("is sleeping...")# 查看類的名稱空間print(LuffyStudent.__dict__)# {'__module__': '__main__', 'school': 'luffycity', 'learn': <function LuffyStudent.learn at 0x00000000025B8B70>, 'sleep': <function LuffyStudent.sleep at 0x00000000025B8BF8>, '__dict__': <attribute '__dict__' of 'LuffyStudent' objects>, '__weakref__': <attribute '__weakref__' of 'LuffyStudent' objects>, '__doc__': None}print(LuffyStudent.__dict__["school"])  # luffycityprint(LuffyStudent.__dict__["learn"])  # <function LuffyStudent.learn at 0x00000000025B8B70># 查print(LuffyStudent.school)  # luffycityprint(LuffyStudent.learn)  # <function LuffyStudent.learn at 0x0000000002158AE8># 增LuffyStudent.country = "China"  print(LuffyStudent.country) #  China# 刪del LuffyStudent.countryprint(LuffyStudent.__dict__)# {'__module__': '__main__', 'school': 'luffycity', 'learn': <function LuffyStudent.learn at 0x0000000002158AE8>, 'sleep': <function LuffyStudent.sleep at 0x0000000002158B70>, '__dict__': <attribute '__dict__' of 'LuffyStudent' objects>, '__weakref__': <attribute '__weakref__' of 'LuffyStudent' objects>, '__doc__': None}# 改LuffyStudent.school = "foguang University"print(LuffyStudent.__dict__)# {'__module__': '__main__', 'school': 'foguang University', 'learn': <function LuffyStudent.learn at 0x0000000002158AE8>, 'sleep': <function LuffyStudent.sleep at 0x0000000002158B70>, '__dict__': <attribute '__dict__' of 'LuffyStudent' objects>, '__weakref__': <attribute '__weakref__' of 'LuffyStudent' objects>, '__doc__': None}
