In a recent article on Dev.to, Python developer Kirf G. highlights the difference between using "raise" and "raise e" when handling exceptions in Python programming. The two methods may seem similar at first glance, but they impact how errors are logged and debugged.

The article explains that when an error occurs within a try block, the code jumps to the except block where we can handle the error gracefully or re-raise it for further handling. In some cases, it's useful to catch an error, log it, and then re-raise the exception to be handled by another part of the program.

The key difference between "raise" and "raise e" is how they handle tracebacks. The article provides a Python script example demonstrating this distinction. It shows that using "raise" keeps the traceback simple and direct, while "raise e" resets the traceback starting point, potentially obscuring the original error location.

The author concludes that in most cases, using "raise" is preferable for simplicity and clarity, as it retains the original traceback. However, there may be rare cases where "raise e" is useful, such as when highlighting a new context for an error.
