Regex in discord.py purge check?

Question

Is it possible to implement a regex check in the check argument of discord.TextChannel.purge?

I believe that I have to use lambda or something, but I'm really not sure. Any example would be appreciated!

I'm using the latest version of both pycord and re.

Lambda can be used. You have to define a method to check if the message matches the Regex.

def matches(message, regex):
    if re.match(regex, message): return True
    return False


#Either get your regex from the command/message content or just set it to a variable.
arg = "\d+" #arbitrary
await ctx.channel.purge(limit=10, check=lambda message, regex=arg: matches(message, regex))

Edit: Fixed code. Was wrong. Now right.
