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 "<stdin>", line 1, in <module>
AttributeError: 'NoneType' object has no attribute 'info'
I CAN, however, do:
logging.info("finished step 4.")
And it works.
What confuses me about this is that I can do something like this:
# call another function and pass it the logger instance:
foo(logging)
And, if I define foo() like this:
def foo(log):
# this works fine!
log.info("finished step 4.")
The log.info works fine inside of foo().
Why is it that I can pass logging as an instance into a function, and
use whatever instance name I wants inside of foo(), but I can't assign
an "alias" for the logging instance inside of main() (by doing instancealias =
logging.basic())?
