python物件風格object & 類class學習筆記

類class

• 一般類的建立

#建立類
class Foo:
	def bar(self):      #self必填
		print('Bar')
		
	def hello(self, name):
		print('I am %s' % name)

obj = Foo() obj.bar obj.hello(‘zzw’)

• 通過建構函式例項化建立

class Foo:
	def __init__(self, name, age): #注意inti前後是雙下劃線__,不是單_
		name = self.name
		age =
 
 self.age
##例項化
obj1 = Foo('zzw', 26)
print(obj1.name)
print(obj1.age)

obj2 = Foo('lg', 25)
print(obj2.name)
print(obj2.age)
