Hi Steven,
Sure, I am going to explain, I was at the social event of PyCon Germany without
my laptop and the code was not really clear on my smartphone. I wanted to know
if there was an indentation issue.
It's also the reason for my big reply with the
James Hewitt added the comment:
So just the fact that somewhere in the function a name is referenced,
even if that code isn't actually executed, is enough to change the local
namespace. I think I knew that, but didn't know that's what it meant :)
I guess the moral is, pay attention to
Steven D'Aprano added the comment:
Yes, that's exactly right. That's how local variables work in Python:
x = 999 # global x
def demo():
if False:
x = 1
x # local x has no value
does the same thing. This is standard, documented behaviour, regardless
of which kind of assignment
James Hewitt added the comment:
I don't quite follow... the 'import logging.config' statement should
never be executed, and if it is commented out the program works fine as
written. It's as if the mere presence of the statement in the code
causes 'logging' to be shadowed inside the

Stéphane, I'm curious why you asked for a pastebin when James already provided
the code right here in the tracker? (Your email even included a copy of that
code.) Why split the information into another website?

Steven D'Aprano added the comment:
This is expected behaviour: import is a form of assignment.
"import logging", like "logging = 1", tells the compiler to treat logging as a
local variable (unless you declare logging as global). As the exception says,
you are trying to access the logging

New submission from James Hewitt :
Having 'import logging.config' in an if statement in a function causes a
namespace issue, despite the fact that the import is not reached.
Example code:
---
#!/usr/bin/env python3
# Test weird import bug
import logging
config = {}
config['log'] = {}
