logging.basicConfig() does not return a logger, it returns None.

By the way, I could have SWORN that I've done this successfully in the past in
another program. I am relatively certain I have used log.LEVEL() in some of my
programs in the past, but I can't figure out how I did it.

I'm working with an instance of a Python logger.
Some code:
log =
logging.basicConfig(level=logging.DEBUG,filename="/home/richard/templog",filemode='w')
Later in my program I do:
log.info("finished step 4.")
Python spits out this error:
Traceback (most recent call last):
File ""
oddly enough, i get different results doing it the "old-fashioned" way:

There are at leasty 3 archives, two of which are searchable.

Dear all-
I am a new-comer to [EMAIL PROTECTED] I guess a lot of my future questions may
have been asked by others already.
As I am a new-comer, I don't have the previous emails.
I wonder whether there is a way for searching for previous questions and
answers so that I don't need to ask si

I dunno, let's check:
>>> import timeit
>>> t = timeit.Timer( "12 ** .5" )
>>> print t.timeit(1000)
2.29147315025
>>> t = timeit.Timer( "sqrt(
Does anyone know which is the more efficient way of
finding a square root in Python:
sqrt(x) or x ** 0.5
???

Is it a bad practice to avoid 0.1 representation errors
(0.101) by just doing the following?

Ok, Here's the problem. You are trying to compare two floating
point numbers. But python stores data in binary and displays
it in decimal.

The subprocess module documentation has several examples
of using both the Popen class and the call function.
