Cooldown For Command On Discord Bot Python

Question

@client.command(pass_context = True)
async def getalt(ctx):
    msg = ["[e-mail]:Cyber123", "[e-mail]:culillo123", "[e-mail]:Albakortoci1", "[e-mail]:toysale22", "[e-mail]:nich918273645", "[e-mail]:Lodelode1", "[e-mail]:emolover123", "[e-mail]:rube541632789mk", "[e-mail]:fryckman22", "[e-mail]:blackout541", "[e-mail]:ploopy101"]
    await client.send_message(ctx.message.author, random.choice(msg))
    await client.send_message(ctx.message.channel, "Alt Has Been Seen To Your DMs")
    await client.purge_from(ctx.message.channel, limit=2)
    await client.send_message(ctx.message.author, "Please Wait 30 Seconds Before Using This Command Again.")

I want to set a 30 sec cooldown for this command.

Answer 1

You should decorate your command with

@commands.cooldown(1, 30, commands.BucketType.user)

This will add a ratelimit of 1 use per 30 seconds per user. docs, example

You can change the BucketType to default, channel or server to create a global, channel or server ratelimit instead, but you can only have 1 cooldown on a command.

Note: In discord.py rewrite (v1.0+) instead of BucketType.server, you have to use BucketType.guild.

This will also cause a CommandOnCooldown exception in on_command_error
