Python TypeError:draw（）正好接受1个参数（给定2个）

我试图在pygame屏幕上显示一个图像，但我不断得到错误：当我运行第二个文件时，TypeError:draw（）正好取1个参数（给定2个）

代码如下：

import pygame
from pygame.locals import *


# Create a class called Person
class Person:
    def __init__(self, newX, newY):        ###defines paramaters###
        self.x = newX
        self.y = newY


    def draw(window):                      ###loads and draws the image###
        img = pygame.image.load("dude.gif")
        window.blit(img, (self.x, self.y))   


    def moveLeft(self):
        # Change x so that the object can move left
        pass



    def moveRight(self):
        # Change x so that the object can move right
        pass



    def moveUp(self):
        # Change y so that the object can move up
        pass



    def moveDown(self):
        # Change y so that the object can move down
        pass

这是第二个文件：

import pygame, sys
from pygame.locals import *
from Person import *

# Creates the screen to draw on
pygame.init()
screen = pygame.display.set_mode((800,600))

# Allows a key that is held down to count as multiple presses
pygame.key.set_repeat(100,100)

# Creates a Person object named guy
guy = Person(50,50)

# Event Loop
while True:
    # Colors the screen white
    screen.fill((255,255,255))

    # Draw your person on the screen
    guy.draw(screen)                            

    # Update the screen
    pygame.display.update()


    # Check for key presses and mouse clicks
    for event in pygame.event.get():
        # Determine if the user has closed the window or pressed escape
        if event.type==QUIT or (event.type==KEYUP and event.key==K_ESCAPE):
            # Quit the program
            pygame.quit()
            sys.exit()

        # Check if an arrow key is pressed and 
        # move guy in the correct direction
        elif event.type==KEYDOWN:

            if event.key==K_UP: 
                guy.moveUp()

            elif event.key==K_DOWN:
                guy.moveDown()

            elif event.key==K_LEFT:
                guy.moveLeft()

            elif event.key==K_RIGHT:
                guy.moveRight()

您的

draw

方法应定义为

def draw（self，window）：

：

---

方法签名中缺少

self

参数

def draw（self，window）：

，而不是

def draw（window）：

@JoshuaTaylor，谢谢——有很多非常类似的问题，但我很难找到一个完全正确的问题。@CharlesDuffy我刚刚用谷歌搜索了

“正好取了1个参数（给定2个）”缺少self

。这个问题是第一个击中目标的问题，我用作欺骗目标的问题是第二个。（哇，谷歌更新内容太快了。）谢谢。我讨厌那种自我的东西那种自我的东西不值得讨厌。是我，也是你。它是面向对象编程的精髓，是一个对象和它的能力之间的参照。我嘴里说的是什么？？？点点头。“显明胜于含蓄”——很像Python的禅意。如果你对我的答案感到满意，那么请考虑点击我的回答，点击嘀嗒记号。

def draw(self, window):
    img = pygame.image.load("dude.gif")

    # and after all, you're using self here
    window.blit(img, (self.x, self.y))
