Python Dictionarys

Question

我被学校项目所困扰。以下函数应该在给定的字典中设置房间的名称。房间dicionary应该保留，因为使用它的函数。它应该随机设置rom的名称，以便稍后在另一个函数中显示它。

import string
import random

names = ['This', 'happens', 'all', 'the', 'time']
for key, value in rooms.items():
    # do something with value
    rooms[value]["name"] = random.choice(names)
    names.remove(rooms[value]["name"])

room_1 = {"name" : "",
          "description" : """ """,
          "exits" : {"east": "Second" , "south":"Fourth"},
          "items" : []}

room_2 = {"name": "",
          "description" : """ """, 
          "exits" : {"west": "First" , "south":"Fifth" , "east":"Third"},
          "items" : []}

rooms = {"First" : room_1,
         "Second" : room_2,}

Answer 1

要使您发布的脚本有效，您需要：

1. 将for lop移动到脚本的末尾（设置值后） rooms）。它在rooms变量上运行，必须对其进行定义 冷杉

2. 修复for循环。如果要修改字典的值，请使用rooms[key]访问它，而不是rooms['value']。

`这样的事情：

import random
names = ['This', 'happens', 'all', 'the', 'time']

rooms = {
    "First": {},
    "Second": {},
}

for key in rooms:
    # do something with value
    name = random.choice(names)
    rooms[key]["name"] = name
    names.remove(name)
