如何使用 on_message_edit 事件来阻止脏话？ (discord.py)

Question

I want my bot to delete the message if someone edits the message into a swear word message using the on_message_edit event, but I've been trying to figure this out and nothing has worked so far. Here is the code that doesn't work.

with open("badwords.txt") as file:
    blacklist = file.read().split('\n')

@client.event
async def on_message_edit(before, after, message):
    for word in blacklist:
        regex_match_true = re.compile(fr"[{symbols}]*".join(list(word)), re.IGNORECASE)
        regex_match_none = re.compile(fr"([{letters}]+{word})|({word}[{letters}]+)", re.IGNORECASE)
        if regex_match_true.search(message.content) and regex_match_none.search(message.content) is None:
            #embed here
            await message.delete()
            break

The on_message_edit event has no message argument. There are arguments before and after , both of which are discord.Message object. As far as I understand, after a message is edited, you are trying to delete it if it contains a blacklist word. You can get the content of the edited message using after.content . You can then check if it contains the word blacklist.

blacklist = open('badwords.txt', 'r').read().split('\n')

@client.event
async def on_message_edit(before, after):
    for word in blacklist:
        if word in after.content:
            await after.delete()
            return

This is a simple example of how you you can do this, but if you want to use regex , you can use it too.

with open("badwords.txt") as file:
    blacklist = [line.strip() for line in file.readlines()]

@client.event
async def on_message_edit(before, after):
    for word in after.content.split():
        if word.lower() in blacklist:
            #embed here
            return await message.delete()
