Python——类的实例化

在C1中实例化RefreshLabels，并将对象传递给C2和C3，当在C2中改变对象某一变量时，在C3中也可以得到该变量的最新值。
class RefreshLabels:
def __init__(self):
self.rect_labels = []

class C1:
def __init__(self):
self.c2 = C2()
self.c3 = C3()
self.refreshLabels = RefreshLabels()
self.c2.refreshLabels = self.refreshLabels
self.c3.refreshLabels = self.refreshLabels

class C2:
def __init__(self):
self.refreshLabels = None

def fun1(self):
