Logging module not working with Python3

Question

I am having issues with the standard logging module. If I open a python2.7 shell and import logging everything works fine:

$ python
>>> import logging
>>>

But if I open a python3.4 shell and import logging I get the following error:

$ python3.4
>>> import logging
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<frozen importlib._bootstrap>", line 2237, in _find_and_load
File "<frozen importlib._bootstrap>", line 2222, in _find_and_load_unlocked

                         ^
SyntaxError: invalid syntax

I have no idea what the problem is and can't seem to find anyone else who has had the same issue.

Why was this downvoted? It's definitely a correct answer

I was trying to add logging==0.4.9.6 in the requirements file of my gfunc xD, and it didn't even show me the error in the logs.

You seem to have installed a third party library called logging in your Python 3 environment, which is hiding the standard library version, and one of its files has a typo.

It's not so much a typo than that it's Python 2 syntax. But yes, that's not the (location of) the built-in logging module.

Thank you both! I deleted logging-0.4.9.6-py3.4.egg from /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/ and now logging is working in both python2 and python3.

I stupidly created a file called logging.py to try out some log features. Then when trying the code below, it is effectively referring to itself and can't find the debug method.

import logging

logging.debug("Debug message")

Changing my file name to logtest.py fixed the problem.

I felt like a clown when I read this and realized that was my issue too. Thank you for sharing!

for me it was the previous install of a logging library under an older Python version.

pip3 uninstall logging

fixed it for me.
