Python Telegram Bot - I can’t send photos

Question

I just started programming, so maybe it’s something simple. Anyway, I made a bot on Telegram to simulate a Pokemon hunt. I’m trying to implement that the bot sends a photo of Pokemon when the user finds it, but I can’t.

import logging, random 
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters

pokemon_list = open("pokemon.txt", encoding="utf8") pokemons = [] for line in pokemon_list:
    pokemons.append(line.strip("\n"))

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

logger = logging.getLogger(__name__)

# command handlers. def start(update, context):
        update.message.reply_text(
        'Olá {}! Nosso mais novo PokeTrainer!'.format(update.message.from_user.first_name))

def help(update, context):
        update.message.reply_text('Bot desenvolvido para simular um encontro aleatório na grama alta,'
                                  ' utilizando os Pokemons da primeira geração.'
                                  '\n/start - Inicia o bot.'
                                  '\n/help - Ajuda do bot.'
                                  '\n/procurar - Procura um Pokemon na grama alta.'
                                  '\nEncontrou algum erro? Envie um email para: [email protected]')

def procurar(update, context):
        pokemon = random.choice(pokemons)
        update.message.reply_text(f"Você encontrou um {pokemon}!")

def send_photo(update, context):
        bot.sendPhoto(
            chat_id=update.message.chat_id,
            photo='1.png')

# Start the bot. def main():
    updater = Updater("1006417815:AAEE1h8QPug18Gu-d5QAHKC57Vjv_StP2G8", use_context=True)
    dp = updater.dispatcher
    dp.add_handler(CommandHandler("start", start))
    dp.add_handler(CommandHandler("help", help))
    dp.add_handler(CommandHandler("procurar", procurar, send_photo))
    updater.start_polling()
    updater.idle()

if __name__ == '__main__':
    main()
