Please don't dump code on us and tell us to ignore parts of it. We're
offering our time and experience without charging you, the least you can
do is take the time to eliminate the irrelevant parts of the code
yourself, and show us the smallest piece of code which demonstrates the
Doing so will not only demonstrate respect for others, but it might even
help you solve the problem yourself.

That's not exactly true, is it? I count at least three other differences:
* facbac-012a.py imports getpass and defines a redundant
getusername function (redundant because all it does is
* it also defines a function destination2 which is different
from destination1, and uses that;
* there's a difference in the call to os.path.isfile;
I don't know if these are relevant.
You say the difference between the script that works and the script that
doesn't is the destination. And then you show an error that appears to be
because the destination doesn't exist:

Seems like an open and shut case to me.

There is no double-backslash in the destination name. Backslashes are
special in Python, and when displaying strings, they are escaped:
>>> s = "x\yz"
>>> print s
Your suggestion, that the problem is that the config directory doesn't
exist, sounds reasonable to me. Only you can test that, as we don't have
access to your file system.
