Python logger.exception()

  • by

Python logger.exception() will output a stack trace alongside the error message. In Python 3 you must call the logging.exception method just inside the except part. If you call this method in an arbitrary place you may get a bizarre exception. The docs alert about that.

except Exception:
    logger.exception("Fatal error in main loop")

Python logger exception()

A simple example code logs a Python error with debug information.

import logging

    1 / 0
except ZeroDivisionError:


Python logger exception()

The multiline message that shows up in your log might look like this:

Fatal error in main loop
Traceback (most recent call last):
  File "", line 14, in
  File "", line 9, in main_loop
  File "", line 4, in foo
    return 10 // n
    ZeroDivisionError: integer division or modulo by zero
