lis中随机变量的选取

Question

我试图从列表中随机选取一个字典变量。我首先从列表emotelist中选择一个随机变量。你知道吗

import random
emotelist = [bored]
emotechosen = random.choice(emotelist)
emotename = emotechosen['emote']
emoteframe = emotechosen['frame']
bored = {'emote':'bored', 'frame':135}
print emotename
print emoteframe

但我收到了一个错误

NameError: name 'bored' is not defined

谢谢你的帮助。在创建变量列表之前，我应该在列表中定义变量。你知道吗

Answer 1

在创建包含它的列表之前，必须定义bored：

import random
# move bored definition here:
bored = {'emote':'bored', 'frame':135}
# now use it in a list construction
emotelist = [bored]
emotechosen = random.choice(emotelist)
emotename = emotechosen['emote']
emoteframe = emotechosen['frame']
print emotename
print emoteframe

Answer 2

看起来您正在尝试打印随机字典值：

from random import choice

bored = {'emote':'bored', 'frame':135}
print bored[choice(bored.keys())]

Answer 3

在使用它之前，您需要定义

import random
bored = {'emote':'bored', 'frame':135}
emotelist = [bored]
emotechosen = random.choice(emotelist)
emotename = emotechosen['emote']
emoteframe = emotechosen['frame']
