所以,如果我有一个班级:
class Person(object):
'''A class with several methods that revolve around a person's Name and Age.'''
def __init__(self, name = 'Jane Doe', year = 2012):
'''The default constructor for the Person class.'''
self.n = name
self.y = year
然后是这个子类:
class Instructor(Person):
'''A subclass of the Person class, overloads the constructor with a new parameter.'''
def __init__(self, name, year, degree):
Person.__init__(self, name, year)
我有点迷失了如何让子类调用并使用name
和year
的父类构造函数,同时在子类中添加新参数degree
。

Python建议使用super()
。
Python 2:
super(Instructor, self).__init__(name, year)
Python 3:
super().__init__(name, year)
