How to print stack trace from a running python application

to print a stack trace from a running python application, you can use the `traceback` module. this module provides functions for extracting, formatting, and printing stack traces. here's a step-by-step tutorial on how to print a stack trace from a running python application:

step 1: import the `traceback` module

step 2: use the `print_exc()` function
the `print_exc()` function from the `traceback` module prints a stack trace from an exception that is currently being handled. you can call this function wherever you want to print the stack trace.

here's an example code snippet:

in this example, when a `zerodivisionerror` occurs, the `print_exc()` function is called to print the stack trace.

step 3: use the `format_exc()` function
if you want to capture the stack trace as a string for logging or further processing, you can use the `format_exc()` function. this function returns the formatted stack trace as a string.

here's an example code snippet:

in this example, the stack trace is formatted as a string and then printed. you can also save this string to a file or log it for debugging purposes.

by following these steps, you can print a stack trace from a running python application. this can be helpful for debugging errors and understanding the flow of your code during runtime.
