Python：在类对象内的字典中更改所有键的索引，而不是仅更改一个键

(两个类别都在帖子的底部) 我试图用Python 创造一个"世界"，从顶部看，世界是由一本字典组成的，就像

WorldDict = 
{
0: ["-","-","-"],
1: ["-","-","-"],
2: ["-","-","-"]
}

我试图将一个玩家"催生"到世界中，并陷入了它"渲染"玩家的部分(将字典上的坐标中的a -更改为p).

这是开始代码:

import WorldClass
import CreatureClass

MyWorld = WorldClass.World(5, 5, "  -")
MyWorld.CreateWorld()

Player = CreatureClass.Creature("  P", "player", 100, 1, 10, 1, "1")

执行MyWorld.PrintWorld()只会以良好的格式打印词典.当前输出:

  -  -  -  -  -
  -  -  -  -  -
  -  -  -  -  -
  -  -  -  -  -
  -  -  -  -  -

问题来了，当我做MyWorld.SpawnCreature(" P", Player)甚至只是直接更改法令时:

coordinates = (1,3)
MyWorld.WorldDict[coordinates[1]][coordinates[0]] = "  P"

它最终会让它看起来像这样:

  -  P  -  -  -
  -  P  -  -  -
  -  P  -  -  -
  -  P  -  -  -
  -  P  -  -  -

有人能告诉我为什么它会影响1处的所有指数而不是仅影响3处的指数吗？ 我想要的:

  -  -  -  -  -
  -  -  -  -  -
  -  -  -  -  -
  -  -  -  -  -
  -  P  -  -  -

我已经在帖子的描述中描述了发生了什么、我想发生什么以及我try 过什么.
