Code to read telegram messages from a user id

This program reads Telegram messages. It uses a config.ini file that stores credentials such as api_id, api_hash, phone number, and username for Telegram connectivity.

Telethon and configparser are the main package dependencies used.

To get your api_id and api_hash, you need to visit Telegram core:

https://core.telegram.org/
my.telegram.org

Then fill in a form containing the information you need and an api_id and api_hash will be provided for you to use.

To get a user's user id:

1. Go to telegram and search for @userinfobot
2. In the bot type /start
3. Forward any message sent by that user
4. The bot returns the user id and user name


-----


Sample config.ini template:

[Telegram]
# no need for quotes

# you can get telegram development credentials in telegram API Development Tools
api_id = api_id_without_quotes
api_hash = hash_without_quotes

# use full phone number including + and country code
phone = +65XXXXXXX
username = Usernamewithoutquotes

If using jupyter, use keyword await [to elaborate more on this]
e.g. await client start()
