How does logging.exception gets hold of the exception?

Question

Given the following code, could some python experts tell me how does logging.exception gets reference to the exception to print it out?

>>> try:
...     1/0
... except:
...     logging.exception("message")
... 
ERROR:root:message
Traceback (most recent call last):
  File "<console>", line 2, in <module>
ZeroDivisionError: integer division or modulo by zero

I am assuming it's going through the traceback to get that exception message, but would be good to hear from the experts.

Answer 1

The logging module got the exception via sys.exc_info() . You could take a look at the source code in logging module
