I don't see code there, I see lots of config data, presumably in an .ini 
file.   So I don't know how you're reading it in, and converting it to 
Python variables, but I know where I'd look, based on your error message.

The following line:

args=("G:\lok_sib\logs\rotate_test", 'midnight', 1)

seems to contain a Python string.  But there are unescaped backslashes 
within it.  You can get away with it in two cases, because \l  isn't a 
valid escape sequence.  But in the case of \r, it looks like a newline 
character.

Anyway, all three of those backslashes probably need to be doubled.

args=("G:\\lok_sib\\logs\\rotate_test", 'midnight', 1)

Two other cures that may work, depending on context:   change the backslashes to forward slashes, or use a raw string.

But as I said earlier, you don't show in any way what code is interpreting this line, so it's all just guesswork.
