關於Python Object繼承的相關總結

在Python中所有的類都繼基類object，基類object擁有__ setattr__()和__ getattribuate__()兩個常用的方法，__ setattr__()用於根據指定的name設定物件中相應屬性的value，而__ getattribuate__()用於通過相應的name獲取物件中相應的屬性的value。 當呼叫 instance.name = value 的形式的時候，預設呼叫instance.__ setattr__(name,value ),而當呼叫以下instance.name形式的時候，預設呼叫instance.__ getattr__(name)方法。

class Book(object):
	'''
	def __init__(self,name,value):
		self.name = name
		self.value = value
	'''
	def __setattr__(self,name,value):
		object.__setattr__(self,name,value)
	def __getattr__(self,name):
		try:
			return object.__getattribute__(name)
		except:
			return name + " is not found!"
	def
 
 __str__(self):
		return self.name + " Meet "+ str(self.value)

def main():
	c = Book()
	# c = Book('Python',"Hello World!")
	c.name = 'Python'
	c.value = "Hello World!"
	c.hello = 'hello'
	print(c.name)
	print(c.value)
	print(c)

if __name__ == '__main__':
	main()

輸出的結果如下所示：

Python
Hello World!
Python Meet Hello World!
