python 类间的有趣调用

代码

class A:
	def __init__(self):
		self.x = 111
		self.y = 'test'
	def testA(self, inp):
		print("in a class")
		print("{}--{}--{}".format(self.x, self.y, inp*2))

class B:
	def __init__(self):
		self.a = A()

	def testB(self):
		print("in b class")
		self.a.testA("la")

class C:
	def __init__(self):
		self.b = B()
		self.a = self.b.a
	def testC(self):
		print("in c class")
		self.a.testA("ready?")
		self.b.a.testA(11)
demo = C()
demo.testC()
