Module 11 of 30
Moderation Commands
Build essential moderation tools: kick, ban, unban, and message clearing.
Why Moderation Matters
Every server needs moderation. Bots handle repetitive tasks like removing spam and managing troublemakers. Discord.py makes this easy with built-in methods.
PYTHON
@bot.command()
@commands.has_permissions(kick_members=True)
async def kick(ctx, member: discord.Member, *, reason="No reason"):
await member.kick(reason=reason)
await ctx.send(f"Kicked {member.mention}")
@bot.command()
@commands.has_permissions(ban_members=True)
async def ban(ctx, member: discord.Member, *, reason="No reason"):
await member.ban(reason=reason)
await ctx.send(f"Banned {member.mention}")
@bot.command()
@commands.has_permissions(manage_messages=True)
async def clear(ctx, amount: int = 5):
await ctx.channel.purge(limit=amount + 1)
await ctx.send(f"Cleared {amount} messages!", delete_after=3)
Q1: What does ctx.channel.purge() do?
Q2: Permission for member.ban()?
Module 12 of 30
Advanced Moderation
Mute system, warning system, and mod-logs.
PYTHON
@bot.command()
@commands.has_permissions(moderate_members=True)
async def mute(ctx, member: discord.Member, time: int, *, reason="No reason"):
await member.timeout(discord.utils.utcnow() + datetime.timedelta(minutes=time), reason=reason)
await ctx.send(f"Muted {member.mention} for {time} min")
Module 13 of 30
Roles Management
Add, remove, and manage roles.
PYTHON
@bot.command()
@commands.has_permissions(manage_roles=True)
async def addrole(ctx, member: discord.Member, role: discord.Role):
await member.add_roles(role)
await ctx.send(f"Added {role.name} to {member.name}")
Module 14 of 30
Database — SQLite
Store persistent data with SQLite3.
PYTHON
import sqlite3
db = sqlite3.connect("bot.db")
cursor = db.cursor()
cursor.execute("CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, discord_id TEXT, xp INTEGER)")
db.commit()
Module 15 of 30
Database — JSON
Lightweight storage with JSON files.
PYTHON
import json
def load_data(): with open("data.json") as f: return json.load(f)
def save_data(data): with open("data.json","w") as f: json.dump(data,f,indent=2)
Module 16 of 30
Leveling System
XP on message, level-ups, and leaderboard.
PYTHON
@bot.event
async def on_message(message):
if message.author.bot: return
xp = random.randint(10, 25)
cursor.execute("UPDATE users SET xp = xp + ? WHERE discord_id = ?", (xp, str(message.author.id)))
db.commit()
await bot.process_commands(message)
Module 17 of 30
Economy System
Wallet, daily rewards, and shop.
PYTHON
@bot.command()
async def daily(ctx):
reward = random.randint(50, 200)
cursor.execute("UPDATE economy SET balance = balance + ? WHERE user_id = ?", (reward, str(ctx.author.id)))
await ctx.send(f"You received {reward} coins!")
Module 18 of 30
Background Tasks
Automate with @tasks.loop().
PYTHON
from discord.ext import tasks
@tasks.loop(minutes=10)
async def change_status():
await bot.change_presence(activity=discord.Game(name="with KODO"))
change_status.start()
Module 19 of 30
Voice Channels
Connect, play audio, and manage voice.
PYTHON
@bot.command()
async def join(ctx):
if ctx.author.voice:
await ctx.author.voice.channel.connect()
await ctx.send("Joined!")
