我正在创建自己的课程。 _Screen.__init__() 采用 1 个位置参数但给出了 4 个类型错误。 我究竟做错了什么？

Question

# Set up the screen
import turtle

class Screen(turtle.Screen()):
# Create and define an object
    def __init__(self, title, bgcolor, height, width, tracer = 0):
        turtle.Screen().__init__(self)
        # Assign attribute to our instance
        self.title = title
        self.bgcolor = bgcolor
        self.height = height
        self.width = width
        self.tracer = tracer

Answer 1

Your issue is that you are trying to inherit from a class instance rather than from a class. Note that when you are doing

class Screen(turtle.Screen()):

you are creating a new instance of the turtle._Screen class.
To fix this error, you just have to inherit from the right class as such:

class Screen(turtle._Screen):

    # Create and define an object
    def __init__(self, title, bgcolor, height, width, tracer = 0):
        
        # Note that here I use super() to access the parent class instead of creating a new instance with turtle.Screen()
        super().__init__(self)

        # Assign attribute to our instance
        self.title = title
        self.bgcolor = bgcolor
        self.height = height
        self.width = width
        self.tracer = tracer

Hope this helps you
