Python类定义

Question

这里有什么问题：

 class Person:
    def __init__(self, name):
        self.name = name

    def greet(self, other_name):
        return "Hi {0}, my name is {1}".format(other_name,name)

为什么它不能正常工作？

Answer 1

你可能意味着：

return "Hi {0}, my name is {1}".format(other_name, self.name)

您错过了self.变量之前的name。

Answer 2

需要在self参数上引用实例上的属性：

def greet(self, other_name):
    return "Hi {0}, my name is {1}".format(other_name, self.name)
