I’m setting up a Telegram bot using Python, and I’ve run into a problem with my script. The code is meant to handle commands and echo user messages, but it throws an error when executed. Here’s a revised version of my code:
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters
def start(update, context):
update.message.reply_text('Hello!')
def echo(update, context):
update.message.reply_text(update.message.text)
def main():
updater = Updater('MY_BOT_TOKEN', use_context=True)
dp = updater.dispatcher
dp.add_handler(CommandHandler('start', start))
dp.add_handler(MessageHandler(Filters.text, echo))
updater.start_polling()
updater.idle()
if __name__ == '__main__':
main()
When I run the script, I see the error:
TypeError: __init__() got an unexpected keyword argument 'use_context'
I’m not sure why this error occurs. Can someone point out what might be going wrong or how to fix it?
hey there! looks like ur using an old version of python-telegram-bot. try updating it with pip install --upgrade python-telegram-bot. that should fix the ‘use_context’ error. if not, double check ur bot token. good luck!
I encountered a similar issue when setting up my first Telegram bot. The error you’re seeing is likely due to an outdated version of the python-telegram-bot library. The ‘use_context’ parameter was introduced in version 12.0, so if you’re using an older version, it won’t recognize this argument.
To fix this, you should update your library. Open your terminal and run:
pip install --upgrade python-telegram-bot
After updating, your code should work as expected. If you still face issues, double-check your bot token and ensure you have the necessary permissions.
Also, a small tip from my experience: consider adding error handling to make your bot more robust. Something like:
try:
updater.start_polling()
except Exception as e:
print(f’Error starting bot: {e}')
This way, you’ll get more informative error messages if something goes wrong during runtime.
The error you’re encountering is a common one when working with python-telegram-bot. It’s likely due to a version mismatch. The ‘use_context’ parameter was introduced in version 12.0, so if you’re running an older version, this error will occur.
To resolve this, you need to update your library. Run ‘pip install --upgrade python-telegram-bot’ in your terminal. This should bring you to the latest version where ‘use_context’ is supported.
If you’re still having issues after updating, check your bot token. Make sure it’s correct and that you have the necessary permissions.
One additional suggestion: consider using a virtual environment for your bot projects. This helps manage dependencies and avoid conflicts between different projects.
