我尝试加载我制作的自定义精灵，但没有任何效果！ 我的错误是：

回溯（最近通话最近一次）：

  File "C:\Users\BenPa\AppData\Local\Programs\Python\Python38-32\Testing pygame.py",line 5,in <module>
    WalkRight = pygame.image.load("./Python38/RPGsprites/RPGsprite_1.png")
pygame.error: Couldn't open ./Python38/RPGsprites/RPGsprite_1.png

我的代码是：

import pygame

pygame.init()

win = pygame.display.set_mode((1000,800))

pygame.display.set_caption("A RPG Game")

WalkRight = pygame.image.load("./Python38/RPGsprites/RPGsprite_1.png")

WalkLeft = pygame.image.load("./C:/Python38/RPGsprites/RPGsprite_4.png")

WalkIdle = pygame.image.load("./C:/Python38/RPGsprites/RPGsprite_0.png")

Background = pygame.image.load("./C:/Python38/RPGsprites/BackGround.png")

请帮助！
