How To Obtain Username, First Name Or Last Name Of A Telegram User With Python-Telegram-Bot?

Question

I'm Creating A Telegram Bot Using Python-Telegram-Bot

I Know That update.message.chat_id Returns The User's Chat ID, But I Need To Know How To Get User's Username Or First Name And/Or Last Name.

I've Found This On Telegram's Documentation But I Don't Know How To Use It ( I Tried bot.getChat(update.message.chat_id) But No Result)

Answer 1

All infomation about user (as username, id, first/last name and profile photos) available from telegram.User object. You can easily get it using telegram.Message

user = update.message.from_user
print('You talk with user {} and his user ID: {} '.format(user['username'], user['id']))

Answer 2

You can use the json file and access information such as username, ID, etc. You can print this file yourself for information about the json file. See the example below.

# pip install python-telegram-bot==12.0.0
from telegram.ext import Updater
from telegram.ext import CommandHandler
updater = Updater('token')

def start(bot, update):
    # print('json file update : ' ,update)
    # print("json file bot : ', bot)
    chat_id = update.message.chat_id
    first_name = update.message.chat.first_name
    last_name = update.message.chat.last_name
    username = update.message.chat.username
    print("chat_id : {} and firstname : {} lastname : {}  username {}". format(chat_id, first_name, last_name , username))
    bot.sendMessage(chat_id, 'text')

start_command = CommandHandler('start',start)
updater.dispatcher.add_handler(start_command)
updater.start_polling()
updater.idle()
