import discord

class MyClient(discord.Client):
	async def on_connect(self):
        print('[LOGS] Connecting to discord!')

    async def on_ready(self):
        print('[LOGS] Bot is ready!')
        print("""[LOGS] Logged in: {}\n[LOGS] ID: {}\n[LOGS] Number of users: {}""".format(self.bot.user.name, self.bot.user.id, len(set(self.bot.get_all_members()))))
        await self.bot.change_presence(activity=discord.Game(name="Weeke is a god!"))
	
    async def on_resumed(self):
        print("\n[LOGS] Bot has resumed session!")

        # don't respond to ourselves
        if message.author == self.user:
            return

        if message.content == 'ping':
            await ctx.send(f'Client Latency: {round(self.bot.latency * 1000)}')

client = MyClient()
client.run('token')

Example 2: python discord py make embed

def userinfo(self, ctx, *, user: discord.Member = None):
        """
        Get information about you, or a specified user.

        `user`: The user who you want information about. Can be an ID, mention or name.
        """

        if user is None:
            user = ctx.author

        embed = discord.Embed(
            colour=utils.user_colour(user),
            title=f"{user.name}'s Stats and Information."
        )
        embed.set_footer(text=f"ID: {user.id}")
        embed.set_thumbnail(url=user.avatar_url_as(format="png"))
        embed.add_field(name="__**General information:**__", value=f"**Discord Name:** {user}\n"
                                                                   f"**Account created:** {user.created_at.__format__('%A %d %B %Y at %H:%M')}\n"
                                                                   f"**Status:** {utils.user_status(user)}\n"
                                                                   f"**Activity:** {utils.user_activity(user)}", inline=False)
        embed.add_field(name="__**Server-related information:**__", value=f"**Nickname:** {user.nick}\n"
                                                                          f"**Joined server:** {user.joined_at.__format__('%A %d %B %Y at %H:%M')}\n"
