我不喜欢 if/elif 语句看起来有多难看。switch/case 语句也好不到哪里去。我发现字典更容易阅读。现在我知道如果每个键绑定到不同的功能时如何处理它，这很容易。但这需要 8 个不同的移动函数（moveNE、moveN、moveNW 等）。所以我想要一个简单的 move_object 函数，它将方向作为参数。但是，我在让这段代码正常工作时遇到了问题，而且我不确定我做错了什么。这是有问题的代码。

一、字典：

self.keybindings = {ord("h"): {"function":self.move_object, 
                               "args":{"thing":self.things[0], "direction":"North"}},
                    ord('j'): {"function":self.move_object,
                               "args":{"thing":self.things[0], "direction":"South"}},
                    ord('g'): {"function":self.move_object,
                               "args":{"thing":self.things[0], "direction":"East"}},
                    ord('k'): {"function":self.move_object,
                               "args":{"thing":self.things[0], "direction":"West"}},
                    ord('y'): {"function":self.move_object,
                               "args":{"thing":self.things[0], "direction":"NorthWest"}},
                    ord('u'): {"function":self.move_object,
                               "args":{"thing":self.things[0], "direction":"NorthEast"}},
                    ord('b'): {"function":self.move_object,
                               "args":{"thing":self.things[0], "direction":"SouthWest"}},
                    ord('n'): {"function":self.move_object,
                               "args":{"thing":self.things[0], "direction":"SouthEast"}},
                    ord('l'): {"function":self.look, "args":{"thing":self.things[0],}},
                    ord('q'): {"function":self.save_game,
                              "args":{"placeholder":0}}}

现在，move_object 函数：

def move_object(self, thing, direction): 
"""I chose to let the Game class handle redraws instead of objects.
I did this because it will make it easier should I ever attempt to rewrite
this with libtcod, pygcurses, or even some sort of browser-based thing.
Display is cleanly separated from obects and map data.
Objects use the variable name "thing" to avoid namespace collision."""
curx = keywords[thing].x
cury = keywords[thing].y
newy = keywords[thing].y + directions[keywords[direction]][0]
newx = thing.x + directions[keywords[direction]][1]
if not self.is_blocked(newx, newy):
  logging.info("Not blocked")
  keywords[thing].x = newx
  keywords[thing].y = newy

最后，应该调用 move_object 函数的代码：

 c = self.main.getch()
  try:
    self.keybindings[c]["function"](self.keybindings[c]["args"])
  except KeyError:
    pass

键绑定在 Game Class init函数中定义，最后的代码块发生在 Game.main_loop()

我已经阅读了几次教程，但我无法弄清楚我做错了什么。我认为我在这里所拥有的会将 args 字典作为 **keywords 传递给 move_object() 函数，但它给了我一个参数错误（预期 2 个参数，收到 1 个）。
