Discord.py bot 在输入另一个命令时从另一个命令发送消息

Question

This is my code for a chatbot:

if 'Hello' or 'hello' in message.content:
    await message.reply((random.choice(hello)))

if 'How are you' or 'how are you' in message.content:
    mention = ' Thanks for asking, ' + message.author.mention + '!'
    await message.channel.send((random.choice(howareyou)) + mention)

However, whenever I type 'hello' or 'how are you' into the chat separately, it sends both messages. How do I fix this?

Answer 1

I think it's because of two reasons:

1. The operator precedence make the interpreter check the in operator before the or operator.
2. For strings, anything that is not an empty string is considered as having the value True if a boolean is asked. You can have more details in the official documentation about what is considered True or False .

To your interpreter, your code looks like:

if True or ('hello' in message.content):
    await message.reply((random.choice(hello)))

if True or ('how are you' in message.content):
    mention = ' Thanks for asking, ' + message.author.mention + '!'
    await message.channel.send((random.choice(howareyou)) + mention)

So:

1. 'hello' in message.content and 'how are you' in message.content becomes True of False depending on the situation
2. 'Hello' or True becomes True or True which will become True . The same is true for 'Hello' or False . The same is true for 'How are you'
3. So your two if will always see that the condition is True and will always execute

To correct your situation simply:

if 'Hello' in message.content or 'hello' in message.content:
    await message.reply((random.choice(hello)))

if 'How are you' in message.content or 'how are you' in message.content:
    mention = ' Thanks for asking, ' + message.author.mention + '!'
    await message.channel.send((random.choice(howareyou)) + mention)
