Telegram bot polling function – Telegram API

This is my first time trying to make a telegram bot.

Code:

import os
import telebot

API_TOKEN = os.getenv('API_KEY')
bot = telebot.TeleBot(API_TOKEN)

@bot.message_handler(commands=['hello'])
def send_welcome(message):
    bot.reply_to(message, "HI!")
bot.polling()

Error:

Traceback (most recent call last):

    raise Exception('Bot token is not defined')
Exception: Bot token is not defined

I am getting this error while running my telegram bot this is my first time. I have seen some tutorials how to make a bot but mine is not working. I have posted my token in .env file and imported it using os.getenv. I am just simply trying to make a simple bot just for my knowledge as I have tried making discord bots and it was great experience and I learned many new languages so I thought why not try this also.

    try this:

    import telebot

    bot = telebot.TeleBot("API_KEY")

    instead of:

    import os
    import telebot

    API_TOKEN = os.getenv(‘API_KEY’)
    bot = telebot.TeleBot(API_TOKEN)

    I’m also new to python and telegram bots, but my first bot is running ok and I see the problem in your code. Your exception tells us Exception: Bot token is not defined. So your script doesn’t get a token from the system var.

    You say that you have your token in .env file. To get os variable from that file first of all we must import a module: from dotenv import load_dotenv.

    Next we must import variables from that file using the function load_dotenv().
    After that we can read our variables with os.getenv. So that line of your code seems to be correct. If there is no variable in the file os.getenv should get it from the os.

    So your code may look like:

    import os
import telebot
from dotenv import load_dotenv

load_dotenv()
API_TOKEN = os.getenv('API_KEY')
bot = telebot.TeleBot(API_TOKEN)

@bot.message_handler(commands=['hello'])
def send_welcome(message):
    bot.reply_to(message, "HI!")
bot.polling()
