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](http://stackoverflow.com/questions/32848251/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](http://stackoverflow.com/questions/5595276/pydev-
eclipse-python-interpreters-error-stdlib-not-found?rq=1) 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!


Answer: 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')
