How do I execute this? :'(

You need to run the following in the command line from the file's folder:
python3 leave_all_telegram_groups.py

Just make sure you have Telethon installed and don't forget to change the api_id, api_hash, and phone on lines 5-7.

hmn
trying to run it
telethon is installed running python 3.9.6
so i keep on getting "ModuleNotFoundError: No module named 'telethon'"

That's weird. I tried running it and didn't get the error.
Did you install telethon with pip3? If not it migth be because you installed it just for python2

help me !

thanks bro

help me !

thanks bro

You need to add the following code below line 8 in your code (phone = ...):
client = TelegramClient(phone, api_id, api_hash)

from telethon.sync import TelegramClient
from telethon.tl.functions.messages import GetDialogsRequest
from telethon.tl.types import InputPeerEmpty

api_id = xxx
api_hash = 'xxx'
phone = '+xxx'

client = TelegramClient(phone, api_id, api_hash)
client.connect()
if not client.is_user_authorized():
client.send_code_request(phone)
client.sign_in(phone, input('Enter the code: '))

chats = []
last_date = None
chunk_size = 200
groups=[]

result = client(GetDialogsRequest(
offset_date=last_date,
offset_id=0,
offset_peer=InputPeerEmpty(),
limit=chunk_size,
hash = 0
))
chats.extend(result.chats)

groups_to_exclude = ['https://t.me/Uniswapchina']

for chat in chats:
try:
if chat.megagroup== True and chat.title not in groups_to_exclude:
client.delete_dialog(chat)
except:
continue

I did that and after entering the code, I got an error like this, can you help me

First, you shouldn't post your API hash, API id, and phone number. Please edit your messages and censor it/remove the image.

You get an error because this account uses two-step verification.
You have two options:

1. Temporarily remove the two-step verification from your account (should be in Settings -> Privacy and Security), run the script, and when it's done re-enable it.
2. Use the following modified code and enter the password when prompted (I removed your API info and phone so don't forget to add it):

from telethon.sync import TelegramClient
from telethon.tl.functions.messages import GetDialogsRequest
from telethon.tl.types import InputPeerEmpty

api_id = 1
api_hash = ''
phone = ''

client = TelegramClient(phone, api_id, api_hash)
client.connect()
if not client.is_user_authorized():
    y = client.send_code_request(phone)
    client.sign_in(phone=phone, password=input('password : '), code=input('code :'), phone_code_hash=y.phone_code_hash)

chats = []
last_date = None
chunk_size = 200
groups=[]

result = client(GetDialogsRequest(
offset_date=last_date,
offset_id=0,
offset_peer=InputPeerEmpty(),
limit=chunk_size,
hash = 0
))
chats.extend(result.chats)

groups_to_exclude = ['https://t.me/Uniswapchina']

    try:
        if chat.megagroup== True and chat.title not in groups_to_exclude:

thank you very much

hi, thanks buddy for helping me, but i have a new thing. What if I have multiple accounts that I want to delete?

api_id = 1
api_hash = '1'
phone = '+1'

api_id = 2
api_hash = '2'
phone = '+2'
..........
.............
.............
api_id = 30
api_hash = '30'
phone = '+30'

Can you guide me how to do that? Thank you very much

@naut20161990 You can put the code inside a loop that runs on a list with the accounts. For example:

from telethon.sync import TelegramClient
from telethon.tl.functions.messages import GetDialogsRequest
from telethon.tl.types import InputPeerEmpty

# A list of lists with user info
users = [ [1, '1', '+1'],  # Stands for [api_id, api_hash, phone]
            [2, '2', '+2'], 
            ... 
            [30, '30', '+30'] ]


for user in users:
    api_id = user[0]
    api_hash = user[1]
    phone = user[2]
    client = TelegramClient(phone, api_id, api_hash)

    client.connect()
    if not client.is_user_authorized():
        client.send_code_request(phone)
        client.sign_in(phone, input('Enter the code: ')) # Enter the login code sent to your telegram 

    chats = []
    last_date = None
    chunk_size = 200
    groups=[]

    result = client(GetDialogsRequest(
                offset_date=last_date,
                offset_id=0,
                offset_peer=InputPeerEmpty(),
                limit=chunk_size,
                hash = 0
            ))
    chats.extend(result.chats)
    """

    groups_to_exclude = ['group title']

it's awesome, it's working fine, again thank you so much

Hi bro, I have a question can you help me?
I want to delete all chat, what should I do, like the picture I attached
Thank you so much bro

@hernandez2016 Delete the mega-group condition on line 37. Your if statement should look like this:
if chat.title not in groups_to_exclude:

@hernandez2016 Delete the mega-group condition on line 37. Your if statement should look like this: if chat.title not in groups_to_exclude:

I followed it but it doesn't seem to work

@hernandez2016 Did you enter the phone, API ID , API hash, and login code?

I did that but just delete the group, all chats are still intact

hi pro

Can you fix this program?
The program i am writing only takes first account and first line in chat.txt file , it does not work with 2nd account ,3 ....n and lines 2,3,...n in file chat.txt .
I need multiple accounts to send messages to botqc321 group and these accounts get message data from file chat.txt , each account will read each line in chat.txt file to send to botqc321 group and will repeat at end of line in file chat .txt
Thanks pro

Thanks for sharing, It didn't work well with me, I developed a new one https://gist.github.com/eramax/2a651152cbbb4c73d9b9e63e869abea9
Best,

Thank you , added some features and made a new one https://gist.github.com/zodwick/46c7fd398e4616ded6dc5e0bc38da9fd , Hope it helps.
