尝试 Python 继承。我需要您帮助解决错误。
我有 2 个班级：Person（超级班级）和 Contact（子班级）。
尝试运行 Contact 时出现以下错误：
"Contact.py", line 3, in <module>
class Contact(Person):
TypeError: module.__init__() takes at most 2 arguments (3 given)
提前致谢
下面是我的代码：
class Person:
__name=""
__age=0
def __init__(self, name, age):
self.__name = name
self.__age = age
def set_name(self, name):
self.__name = name
def set_age(selfself, age):
self.__age = age
def get_name(self):
return self.__name
def get_age(selfself):
return self.__age
def getInfo(self):
return "Name is: {} - Age is: {}".format(self.__name, self.__age)
# ----------------------------------------------------
import Person
class Contact(Person):
__method=""
def __init__(self, name, age, method):
super().__init__(name, age)
self.__method = method
def set_method(self, method):
self.__method = method
def get__method(self):
return self.__method
def getInfo(self):
return "Name is: {} - Age is: {} - Contact Info: {}".format(self.__name, self.__age, self.__method)
person2 = Contact("Adam Smith", 19, "Email: [email protected]")
print(person2.getInfo())
首先，缩进搞砸了！
如果 Person 在单独的文件中，请导入不带扩展名的文件名，如下所示：
class Person:
def __init__(self, name, age):
self.__name = name
self.__age = age
def set_name(self, name):
self.__name = name
def set_age(self, age):
self.__age = age
def get_name(self):
return self.__name
def get_age(self):
return self.__age
def getInfo(self):
return "Name is: {} - Age is: {}".format(self.__name, self.__age)
# ----------------------------------------------------
from person import Person # assumed your Person class is in person.py
class Contact(Person):
__method=""
def __init__(self, name, age, method):
super().__init__(name, age)
self.__method = method
def set_method(self, method):
self.__method = method
def get__method(self):
return self.__method
def getInfo(self):
return "Name is: {} - Age is: {} - Contact Info: {}".format(self.get_name(), self.get_age(), self.__method)
person2 = Contact("Adam Smith", 19, "Email: [email protected]")
print(person2.getInfo())
通过其方法访问父类的私有字段。
