hi there, i have this code in my main.py :

from telebot import TeleBot

bot = TeleBot(token="my_bot_token", parse_mode="MARKDOWN")

if name == 'main':
bot.infinity_polling()

and i have this code in my start.py :

from main import bot

@bot.message_handler(commands=['start'])
def start(message):
bot.reply_to(message, "Hi, how are you doing?")

for some reason when i run main.py and send /start command to the bot it dosen't response but when i put the main.py and start.py in the same file it works fine
can you explain to me why is this hapening and what is the silultion because i want them seperated
