How to ban users using discord.py?

Question

I wanted to know how to ban members on discord server using following command $ban and then name of the user I want to ban {member.name} and then the reason why he got banned. Also send the personal bot-message to banned user with the reason why he got banned (the reason I typed in console after {member.name}). And I was thinking about making this command in on_message because I write a lot of my commands there. I tried using this (not in on_message):

@client.command(pass_context = True)
async def mute(ctx, member: discord.Member):
     if ctx.message.author.server_permissions.administrator or ctx.message.author.id == '194151340090327041':
        role = discord.utils.get(member.server.roles, name='Muted')
        await client.add_roles(member, role)
        embed=discord.Embed(title="User Muted!", description="**{0}** was muted by **{1}**!".format(member, ctx.message.author), color=0xff00f6)
        await client.say(embed=embed)
     else:
        embed=discord.Embed(title="Permission Denied.", description="You don't have permission to use this command.", color=0xff00f6)
        await client.say(embed=embed)

but I couldn't ban anyone. It doesn't seem to work. Please help me and don't delete this question.

Answer 1

try this code to ban:

@client.command(alaises=['Ban'])
async def ban(ctx, member: discord.Member, *, reason=None):
    await member.ban(reason=reason)
    await ctx.send(f'''"{member}" has been kicked by "{ctx.author}" with the reason "{reason}"''')

Answer 2

I would be giving you the code with comments inside telling the use of it.

This is the code for the bot that I used.

import discord
from discord.ext import commands

mybot = commands.Bot(command_prefix='$',
                    help_command=None) # help_command to disable the default one created by this library.

@mybot.event
async def on_ready(): # To confirm that BOT is online.
    print('I am not online. Let\'s try not to crash today, shall we?')

@mybot.command()
@commands.has_permissions(kick_members=True, ban_members=True, manage_roles=True) # Setting permissions that a user should have to execute this command.
async def ban(ctx, member: discord.Member, *, reason=None):
    if member.guild_permissions.administrator: # To check if the member we are trying to mute is an admin or not.
        await ctx.channel.send(f'Hi {ctx.author.name}! The member you aer trying to mute is a server Administrator. Please don\'t try this on them else they can get angry! :person_shrugging:')

    else:
        if reason is None: # If the moderator did not enter any reason.
            # This command sends DM to the user about the BAN!
