python print stack trace from exception

Title: Python Tutorial: Printing Stack Trace from Exceptions
Introduction:
In Python, understanding and debugging errors is a crucial part of the development process. When an exception occurs, Python provides a traceback, which is a detailed report of the call stack at the point where the exception occurred. Printing the stack trace can be immensely helpful in identifying the root cause of errors. In this tutorial, we will explore how to print the stack trace from exceptions using Python.
Step 1: Basic Exception Handling
Let's start with a simple Python script that raises an exception:
This script defines a function divide_numbers that divides two numbers. Inside the try block, we call this function with 10 and 0, causing a ZeroDivisionError exception. In the except block, we catch the exception and print a generic error message.
Step 2: Printing the Stack Trace
To print the stack trace along with the exception, we can use the traceback module. Update the script as follows:
Step 3: Customizing Exception Handling
You can also selectively catch and print stack traces for specific exceptions. For example:
In this example, we catch ZeroDivisionError separately and print a specific message for that error. For any other exceptions, a generic message is printed.
Conclusion:
Printing stack traces from exceptions in Python is a valuable technique for debugging and understanding the flow of your code during error scenarios. By utilizing the traceback module, you can gain insights into the call stack and pinpoint the source of issues more effectively.
