Discord 机器人的 Python 中的 CommandError

client.run(os.getenv('TOKEN'))
# This client.run is to run the bot we put our bot's token which is genrated during it's creation.
# Token acts as password of bot it should not been shared 
# we did not pasted token here because in repl.it we creat .env extinsion file to make our token hidden 
# os.getenv is used to access the token from env file
# it not nessury to use TOKEN it just like variable 

# when we are doing this localy we do not need .env file to use token we can normaly paste token here in repl we are doing publical that is why it is env and os to access token from env.

1. 此代码适用于 Discord 机器人，其中包含“hello”（机器人在此命令上打招呼）、“inspire”（机器人在此命令上给出随机灵感引用）等命令。 “new!”（如果有用户想添加他自己的鼓励引用或语句），“del！”（如果用户在 new! 命令中添加了错误的内容，则用户可以使用 del! 命令删除它）。

2. 当用户从我们的“sad_words”命名列表中写下一些悲伤的词时，机器人也会抛出一些鼓舞人心的引语。

3. 我在新的时候面临一个问题。 尝试使用命令它应该会确认“新的令人鼓舞的消息不学习”，但它碰巧没有工作。

4. 我无法得到我该如何解决它

5. 代码中的注释将解释整个代码

6. 错误如下：

Answer 1

在第 28 行访问db的键'encouragements'时，您似乎错过了引号：

db['encouragements'] = [cheering_up_message]
