This repository contains code for a chatbot implemented in Python using the Telegram Bot API. The chatbot is designed to respond to user messages and provide assistance based on the input.

To run the chatbot, ensure you have the following:

1. Python 3.7 or above installed on your machine.
2. python-telegram-bot library. Install it using pip install python-telegram-bot.
3. A Telegram bot token. You can obtain one by creating a new bot through the BotFather on Telegram. Note down the bot token for later use.

1. Clone the repository to your local machine or download the source code.
2. Install the required dependencies by running pip install -r requirements.txt in the project directory.
3. Set up environment variables:
   • Create a .env file in the project directory.
   • Add the following variables to the .env file:

     BARD_TOKEN=<your_bard_token>
     TELEGRAM_BOT_TOKEN=<your_telegram_bot_token>
     USER_ID=<your_user_id>
     

     Replace <your_bard_token> with the token for your Bard chatbot and <your_telegram_bot_token> with the token for your Telegram bot. <your_user_id> should be replaced with your Telegram user ID.
4. Run the chatbot by executing python bot/main.py.

The repository has the following structure:

bot/
  ├── bard.py
  ├── helper.py
  ├── main.py

requirements.txt

• bot/bard.py: Contains the implementation of the Bard class, which initializes the chatbot and processes user input to generate responses.
• bot/helper.py: Provides a helper function is_user to check if a user is authorized to use the bot.
• bot/main.py: The main file that sets up the Telegram bot, handles incoming messages, and triggers the chatbot for generating responses.

1. Start the bot by running python bot/main.py.
2. Open the Telegram app and search for your bot using the username you assigned to it during creation.
3. Start a chat with the bot and interact with it by sending messages.
4. The bot will process your input and provide a response based on the implemented logic.
5. You can use the /start command to initiate a conversation with the bot.
6. If you need to reset the chat history, you can use the /reset command.

Note: The bot will only respond to authorized users whose Telegram user ID matches the one specified in the .env file.

You can customize the behavior and responses of the chatbot by modifying the code in bot/bard.py. You can add new functionalities or change the logic to suit your requirements.
