Error using python logging from Pydev

Question

I am using PyDev with Python 3.5 from Aptana installation. All worked fine until I decided to explore logging module, which I never used before. I started with new script from the tutorial:

import logging
logging.warning('Watch out!')  # will print a message to the console
logging.info('I told you so')  # will not print anything

in Pydev I have this error:

Traceback (most recent call last):
  File     "C:\Users\Tomasz\workspace\basicLogging.py", line 7, in <module>
    logging.warning('Watch out!')  # will print a message to the console
AttributeError: module 'logging' has no attribute 'warning'

I searched and found questions like: python : install logging module with similar problem but no solution. Obviously the problem is not with installation. When I run exactly the same script from CMD I have correct output. At the moment it seems like Pydev gives me error on most of my scripts. If I come back to the code wich previously worked fine, now I have this:

Traceback (most recent call last):

    class _CapturingHandler(logging.Handler):
AttributeError: module 'logging' has no attribute 'Handler'

I am not sure how this happened. If I do print(sys.executable) it gives the same path C:\Users\Tomasz\AppData\Local\Programs\Python\Python35-32\python3.exe in both cases, CMD running fine and Pydev giving error.

I have some problem with some python variables in Pydev (I think) but can't find how to fix it.

EDIT: I look at this question and tried the answers

Location of python interpreter is correct and it looks like I have all libs what I need

C:\Users\Tomasz>python3 -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())"
C:\Users\Tomasz\AppData\Local\Programs\Python\Python35-32\Lib\site-packages

And site-packages are already in System PYHONPATH

I tried Restore Defaults in Window -> Preferences -> PyDev -> Iterpreters -> Python Interpreter

EDIT: Following @Samuel advise I try:

import logging

logger = logging.getLogger()
logger.setLevel(logging.DEBUG)

logging.warning('Watch out!')  # will print a message to the console
logging.info('I told you so')  # will not print anything

and in PyDev I have:

Traceback (most recent call last):
  File "C:\Users\Tomasz\workspace\SCT2python\goodExamps\logging\basicLogging.py", line 3, in <module>
    logger = logging.getLogger()
AttributeError: module 'logging' has no attribute 'getLogger'

It works fine if I run it in command line as a script!!

EDIT: THE SOLUTION Thanks to @Samuel I figure out I made absolutely stupid mistake! Before I started playing with the library I made a folder to keep my scripts and stupidly I called it "logging". Obviously renaming the folder solved the problem!

Looks like something overshadowing build-n logger lib. Do you have other modules called `logging` in your project? If not, go to declaration of `logging` and tell me which file is opened — Samuel, May 24 '16 at 07:22

You need to init your logger instance:

import logging

logger = logging.getLogger()
logger.setLevel(logging.DEBUG)

logger.warning('Watch out!') 
logger.info('I told you so')

It does not change anything. I still have an error: `AttributeError: module 'logging' has no attribute 'getLogger'` – tomasz74 May 24 '16 at 07:15
