Discord.py message.content.find multiple words

  discord.py, python

Simple question, probably not so simple answer. Can I make the bot answer to more words, not only "Hi"? In example, message.content.find would have multiple words that would execute the event.

Here’s the code:

async def on_message(message):

    if message.content.find("Hi") >= 0:
        channel = message.channel
        await message.channel.send("Hello!")

        def check(m):
            return m.content != "x" and m.channel == channel

        msg = await client.wait_for("message", check=check)
        await message.channel.send("How are you?".format(msg))
