python telegram bot local variable referenced before assignment – Telegram API

I’m trying to make a code that will include both a conversation with a bot and a command that will cause the bot to send an image but I always get the same error

These are parts of the code.

import logging
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
                     level=logging.INFO)
logger = logging.getLogger()



from telegram import (ReplyKeyboardMarkup, ReplyKeyboardRemove)
from telegram.ext import (Updater, CommandHandler, MessageHandler, Filters,
                          ConversationHandler)
from telegram.ext import Updater
updater = Updater(token='Token', use_context=True)
dispatcher = updater.dispatcher
from telegram.ext import CommandHandler
import telegram
bot = telegram.Bot('Token')

logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
                    level=logging.INFO)

def sic(update, context):
    chat_id=update.effective_chat.id
    file = r"C:UsersYoavDesktopsicily_botuser_photo.jpg"
    bot.send_photo(chat_id, photo=open(file, 'rb'))
    bot.send_photo(chat_id, 'https://bitcoin.org/img/icons/opengraph.png')

def main():
    updater = Updater("Token", use_context=True)
    dp = updater.dispatcher
    conv_handler = ConversationHandler(
        entry_points=[CommandHandler('start', start)],
        
        states={
            LOOKS: [MessageHandler(Filters.regex('^(Mehh|Okay.|Great|Amazing)$'), looks)],

            PHOTO: [MessageHandler(Filters.photo, photo),
                    CommandHandler('skip', skip_photo)],

            EDUCATION: [MessageHandler(Filters.text & ~Filters.command, education),
                       CommandHandler('skip', skip_education)],

            BIO: [MessageHandler(Filters.text & ~Filters.command, bio)]
        },

        fallbacks=[CommandHandler('cancel', cancel)], 
    )
    dp.add_handler(conv_handler)
    dispatcher.add_handler(sic)
    sic = CommandHandler('sic', sic)
    
    updater.start_polling()
    updater.idle()
    
if __name__ == '__main__':
    main()

I always get this error:

Traceback (most recent call last):
  File "C:UsersYoavDesktopsicily_botbot_comb.py", line 161, in <module>
    main()
  File "C:UsersYoavDesktopsicily_botbot_comb.py", line 151, in main
    dispatcher.add_handler(sic)
UnboundLocalError: local variable 'sic' referenced before assignment

how can i fix this?

thanks in advance

    Well, why don’t you swap the line with dispatcher.add_handler and the one with sic = CommandHandler?

    sic = CommandHandler('sic', sic)

    Is your intention with this line to override the sic function?

    If you want to override the function, you should mark sic as a global variable:
    [option 1]

    def main():
    global sic
    ... # same as original

    if that’s not your intention, don’t assign to sic. I don’t know the telegram library, but my guess is that CommandHandler objects are supposed to be passed to dispatcher.add_handler. That means you should change your code to:

    [option 2]

    dispatcher.add_handler(CommandHandler('sic', sic))
