Chat-pdf

Discription This Python script is a Telegram bot that allows users to send a PDF file to be edited. The bot responds to two commands: /start and /edit. Here's a description of the code:

1. Imports: The necessary libraries and modules are imported. These include logging for logging information, os for interacting with the operating system, and the telegram.ext module for working with the Telegram Bot API. Additionally, the pypdf2 library is imported for working with PDF files.

2. Logging Configuration: Logging is configured to display information about the bot's activity.

3. Command Handlers:

   • start(update, context): This function is called when the user sends the /start command. It replies with a welcome message.

   • edit_pdf(update, context): This function is called when the user sends the /edit command. It downloads the PDF file sent by the user, opens it using PyPDF2, applies an example edit (adding a watermark), saves the edited file, sends it back to the user, and then deletes the temporary files.

4. Main Function:

   • main(): This function sets up the Updater, adds the command handlers, starts the bot, and allows it to continuously poll for updates.

5. Token:

   • The TOKEN placeholder should be replaced with the actual token provided by the BotFather when you create a bot on Telegram.

This script creates a basic PDF editing bot. Keep in mind that for more complex edits or additional functionalities, you may need to expand on the edit_pdf function and potentially incorporate other libraries or services. Additionally, ensure that you have the necessary permissions and packages installed on your system for the script to run successfully.
