How Can I Catch and Print Python Exception Tracebacks Without Stopping Program Execution?

Catching and Printing Python Exception Tracebacks Without Program Interruption

In this programming question, we explore the need to capture and log exceptions during program execution without interrupting the program flow. We aim to print the complete exception traceback, including the exception name, details, and stack information.

The provided solution leverages Python's traceback.format_exc() function. This function produces an informative string representation of the traceback. Here's an example that demonstrates its usage:

import traceback

def do_stuff():
    raise Exception("test exception")

try:
    do_stuff()
except Exception:
    print(traceback.format_exc())

This code, when executed, prints the following output:

Traceback (most recent call last):
  File "<module>", line 9, in <module>
    do_stuff()
  File "<module>", line 5, in do_stuff
    raise Exception("test exception")
Exception: test exception

By integrating traceback.format_exc(), we can effortlessly capture and print exception tracebacks without halting or exiting the program. This is especially useful for logging and debugging purposes, providing detailed information about the origin of the exception.
