How can a Discord bot in Python on Discord.py display an error about a command not found in the chat?

Question

Python

When running an unknown command, the bot writes to the running console:
Ignoring exception in command None:
discord.ext.commands.errors.CommandNotFound: Command "habr" is not found

I already did error handling with the kick command, but only one command is covered there.
How to output the .CommandNotFound error is not clear.

p.s. I found the answer. I publish to anyone who needs
# Command not found
@client.event
async def on_command_error(ctx, error):
if isinstance(error, commands.CommandNotFound):
await ctx.send(embed = discord.Embed(description = f'{ctx.author .name}, command not found!', color = discord.Color.red()))

Answer 1

If it's not too late here

@client.event
async def on_command_error(ctx, error):
    if isinstance(error, commands.CommandNotFound ):
        await ctx.send(embed = discord.Embed(description = f'** {ctx.author.name}, данной команды не существует.**', color=0x0c0c0c))

Answer 2

What is 'discord.ext.commands.errors.CommandNotFound' - is this an exception? (I have not worked with Discord)
If yes, then probably like this:

try:
  тут код обработки команд
except discord.ext.commands.errors.CommandNotFound:
  # Здесь код выполнится только при ошибке CommandNotFound
