Python TypeError: draw() takes exactly 1 argument (2 given)

Question

我试图让图像出现在 pygame 屏幕上，但我不断收到错误消息：TypeError: draw() takes exactly 1 argument (2 given) when I 运行第二个文件。

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)::

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))
