Catch and print full Python exception traceback without halting/exiting the program

In Python, you can catch exceptions and still keep the program running by using a try-except block. But to print the full traceback (not just the error message), you’ll want to use the built-in traceback module. This allows you to diagnose the issue without crashing the entire script.

 Basic Example Using traceback.print_exc()

import traceback

try:

    result = 10 / 0

except Exception:

    print("An error occurred, but continuing program...")

    traceback.print_exc()

• Shows the full traceback, line numbers, and error type
  
• Program continues running after printing the error
  

 Logging Instead of Printing (Recommended for real apps)

You can log the traceback to a file or console:

import logging, traceback

logging.basicConfig(filename="errors.log", level=logging.ERROR)

try:

    open("unknownfile.txt")

except Exception as e:

    logging.error("Exception occurred:

%s", traceback.format_exc())

 Why Use This Approach?

• Debug errors without halting automation tasks
  
• Useful in long-running scripts (web servers, schedulers, data pipelines)
  
• Helps trace issues later through logs
  

 Alternative: Access the exception object

except Exception as e:

    print(e)  # shorter but less detailed

By combining try-except with the traceback module, you maintain full visibility into errors while keeping your program alive — a powerful technique for building resilient Python applications.
