就我而言，这是我在运行代码时遇到的错误：

TypeError: __init__() missing 1 required positional argument: 'Screen'

现在通常这很容易解决，但由于某些奇怪的原因，我似乎无法解决问题。我曾经有一段非常好的代码，但现在我开始弄乱它，我的代码现在充满了错误。我会回到我的旧代码，但是一旦我解决了错误，这个新代码将比旧代码好得多。嘿，就像他们说的那样，“你必须一步一步地采取一切措施”。

代码（很抱歉给出这么大的代码，但我不知道您是否需要完整的代码）：

import pygame
import sys
from pygame.locals import *

white = (255,255,255)
black = (0,0,0)
objs = []
MAIN_BUTTON = 1


class Pane():

    def __init__(self, textToDisplay, coordinates, screen):
        self.textToDisplay = textToDisplay
        self.coordinates = coordinates
        self.screen = screen

    def drawPane(self):
        self.screen.blit(self.font.render(textToDisplay, True, (black)), (250, 115))
        pygame.draw.rect(self.screen, (black), self.coordinates, 2)
        pygame.display.update()


class Screen():

    #constants/array(?) outlining the x,y boundaries of each of x10 panes

    #Remember to change co-ordinate values
    #number of panes

        Screen = pygame.display.set_mode((1000,600), 0, 32)

提前感谢您的时间和精力。

看起来你的Screen类的构造函数有一个流氓参数：

def __init__(self, Screen): <-- the 'Screen' here is causing the issue.

That's what your error message seems to be saying. Remove the 'Screen' param as otherwise Python thinks that is a positional (named) parameter.

As as aside: I'd also recommend reading through the Python style guide (Google for PEP-8). You appear to use casing reserved for classes for variables and does make the code less readable for anyone that's written Python for any reasonable length of time.
