不是真的。表达这一点的Pythonic方法可能是以下之一。

普通的老班

class StudentName:
    def __init__(self, first_name, last_name):
        self.first_name = first_name
        self.last_name = last_name

student2 = StudentName(first_name="Craig", last_name="Playstead")

(您还可以添加 , *, self 要强制用户拼写关键字名称,请参见 Keyword (Named) Arguments in Python

无名夫妇

import collections
StudentName = collections.namedtuple("StudentName", "first_name last_name")

student2 = StudentName(first_name="Craig", last_name="Playstead")

student2[0] 访问 first_name [1] 对于 last_name

A. dataclass

import dataclasses

@dataclasses.dataclass
class StudentName:
    first_name: str
    last_name: str

student2 = StudentName(first_name="Craig", last_name="Playstead")

class StudentName:
    def __init__(self, firstname, lastname):
         self.firstname = firstname
         self.lastname = lastname


name = StudentName('firstname', 'lastname')

如果要特别设置构造函数中的哪个属性:

class StudentName:
    def __init__(self, firstname='', lastname=''):
         self.firstname = firstname
         self.lastname = lastname


name = StudentName(firstname='firstname', lastname='lastname')

然后还可以创建一个 StudentName StudentName() . 他的名字和姓氏都是 ''

可以在中定义默认值 __init__ 构造函数等价的方法

class Student():
  def __init__(self, firstname, lastname):
    self.firstname = firstname
    self.lastname = lastname

  def __str__(self):
     return "My name is {} {}".format(self.firstname, self.lastname)

s1 = Student("John", "Smith")
print(s1)
