类的未解析特性引用，代码照着书上打的，实在搞不懂了。

Question

class Man:
    def __init__(self, name):
        self.name = name
        print("Initialized!")


def hello(self):
    print("Hello " + self.name + "!")


def goodbye(self):
    print("Goodbye " + self.name + "!")


m = Man("Klepetan")
m.hello()
m.goodbye()

最后hello(）和goodbye()提示未解析的特性引用
麻烦大家帮忙回答一下，感谢！

Answer 1

函数要缩进啊

 
class Man:
    def __init__(self, name):
        self.name = name
        print("Initialized!")
 
 
    def hello(self):
        print("Hello " + self.name + "!")
 
 
    def goodbye(self):
        print("Goodbye " + self.name + "!")
 
 
m = Man("Klepetan")
m.hello()
m.goodbye()
