What is the best way to log a Python exception?

We import the logging module and then use the logging.exception method to create a log of the python exception.

import logging
try:
print 'toy' + 6
except Exception as e:
logging.exception("This is an exception log")

We get the following output

ERROR:root:This is an exception log
Traceback (most recent call last):
File "C:/Users/TutorialsPoint1/PycharmProjects/TProg/Exception handling/loggingerror1.py", line 3, in <module>
print 'toy' + 6
TypeError: cannot concatenate 'str' and 'int' objects

It is noted that in Python 3 we must call the logging.exception method just inside the except part. If we call this method in any other place we may get a weird exception as per alert by python docs.
