print(b1.get_name4())
print(b2.get_name4())
print(b3.get_name4())

掉坑里了。
ps:

def create_app(self, name):
        if name not in self.apps:
            self.apps[name] = B(name)
        return self.apps[name]

def create_app(self, name):
if name not in self.apps:
self.apps[name] = B(name)
return self.apps[name]
这段有问题么~
