一个python类的简单例子

class People(object):
    def __init__(self) -> None:
        self.name=__class__.__name__
        print("初始化")
        print("start......")
    def setage(self,age):
        print("年龄是-->:%s" %age)
    def getname(self):
        return self.name

p=People()
p.setage(10)
print(p.getname())
# TypeError: People.setage() takes 1 positional argument but 2 were given
# 解决方法类函数中添加self
