Python: 为什么控制台显示错误接受参数？

Question

我是一名新程序员 python，我正在练习对象编程..我有下一个代码：

class Vehiculos():

def __int__(self, marca1, modelo1):

    self.marca = marca1
    self.modelo = modelo1
    self.enmarcha = False
    self.acelera = False
    self.frena = False

def arrancar(self):

    self.enmarcha = True

def acelerar(self):

    self.acelera = True

def frenar(self):

    self.frena = True

def estado(self):

    print("La marca es:", self.marca1)
    print("El modelo es: ", self.modelo1)

class Moto(Vehiculos):
pass

mimoto = Moto("BMW", "CR1")
mimoto.estado()

控制台显示：

Traceback (most recent call last):
File "herencia_new_file.py", line 31, in <module>
mimoto = Moto("BMW", "CR1")
TypeError: Moto() takes no arguments

soo，我想知道怎么了？因为我在一门课程中看到代码和老师工作得很好

首先，你在__int__中有一个错字（应该是__init__），另外，你在estado方法中还有另一个错误，你正在访问属性marca1 和 modelo1 当你应该访问 marca 和 modelo:

class Vehiculos():
  def __init__(self, marca1, modelo1):
    self.marca = marca1
    self.modelo = modelo1
    self.enmarcha = False
    self.acelera = False
    self.frena = False

  def arrancar(self):
    self.enmarcha = True

  def acelerar(self):
    self.acelera = True

  def frenar(self):
    self.frena = True

  def estado(self):
    print("La marca es:", self.marca)
    print("El modelo es: ", self.modelo)

class Moto(Vehiculos):
  pass

mimoto = Moto("BMW", "CR1")
mimoto.estado()
"""
La marca es: BMW
El modelo es:  CR1
"""

Python: Why the console show me an error take arguments?
