关于python attribute error

class Ball:
    def __init__ (self, name): #检查过是两个_
        self.name = name
        def kick(self):
            print ('%s, who kick me?' % self.name)

b = Ball ('potato') #这个没报错
b.kick () #这个开始'Ball' object has no attribute 'kick'

解决方法：

检查缩进

class Ball:
    def __init__ (self, name): #检查过是两个_
                self.name = name
    def kick(self):
                print ('%s, who kick me?' % self.name)
