Newbie here. I may be missing something obvious, in which case,
please feel free to berate and laugh at me.

Here's a dubious line of code:
logging = logging.getLogger(__name__)

How can I refer to the original logging package "logging" after this
statement is run? Specifically, I'm trying to add a log handler with
logging.addHandler(x) and it is of course failing.

Thanks,
Brian

Change it to something like logger = logging.getLogger(__name__), then
logger.addHandler(x). If you don't do this, your logging shadows the
logging module so you won't get very far.

HTH.

Dubious indeed. As a workaround you can import the module again, preferably
under another name:

import logging as real_logging_module

You can think of

import logging

as a shortcut for

logging = __import__("logging")

and of

import logging as x

as a shortcut for

x = __import__("logging")

Hmm, this shouldn't fail, as there is a Logger.addHandler() method whereas
the logging module doesn't contain an addHandler() function:

>>> import logging
>>> logging.addHandler
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'addHandler'
>>> logging.getLogger().addHandler
<bound method RootLogger.addHandler of <logging.RootLogger instance at
0x7f06bdc71a28>>

It's better just to use another variable name - e.g. "logger", Shirley?

Hi Mark -

I thought that would be the answer.

I asked because I'm working with a framework where logging is
similarly renamed in almost every file. The framework is under
development so refactoring is an option.

I'm coming to Python from Java. I'm still getting a feel for scoping
limits. For the sake of curiosity, is there another way to refer to a
package besides name?

Thanks,
Brian
