Hide error stack traces from console output in Python Telegram bot application

I’m developing a Telegram bot with Python and need assistance with handling errors

My bot application frequently displays excessively long stack traces in the terminal whenever there are network problems. I would prefer to conceal these from appearing in the console but still retain them in a file for future debugging.

Here’s my current logging configuration:

import logging

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

When I simulate network failures by disconnecting my internet, I receive extensive stack traces that repeat multiple times. The same NetworkError shows up four times consecutively, which clutters my console output.

My objectives are:

  1. Conceal the complete stack trace from the terminal output
  2. Log these errors to a text file instead
  3. Display only one instance of duplicate errors

I’ve attempted various solutions I found online regarding hiding tracebacks with debug flags, but they haven’t worked with my Telegram bot configuration. The error handling seems to be originating from the telegram library itself.

Has anyone encountered this before? What’s the best approach to streamline error output while still maintaining the error details for debugging?

I faced similar challenges while developing my own Telegram bot. The issue arises because the telegram library handles errors on its own, which can conflict with standard logging settings. A solution that proved effective for me involved defining a custom error handler. By implementing a FileHandler for logging errors to a file and modifying the console output to display only essential information, I was able to reduce clutter. Additionally, I created a method to log duplicate errors only once within a specific timeframe by keeping track of recent errors. Focusing on modifying the error handling at the library level is crucial, particularly utilizing the error callback provided by the telegram bot for this purpose.

What worked for me was setting up multiple logging handlers with different levels and output destinations. You can configure one handler to write everything to a file while keeping console output minimal.

Try creating separate handlers like this - one FileHandler with DEBUG level that captures all stack traces to a log file, and a StreamHandler for console with WARNING level that only shows brief messages. Set the root logger to DEBUG so it catches everything, but each handler filters what it displays.

For duplicate suppression, I implemented a simple cache that stores error hashes and timestamps. Before logging, check if the same error occurred recently and skip it if found. This prevents the repetitive NetworkError spam you mentioned.

The key insight is that telegram library errors bypass your basic logging config, so you need to intercept them at the handler level rather than trying to suppress tracebacks globally. This approach lets you maintain full debugging capability in files while keeping your terminal clean during development.
