You probably should use / as your directory separator in Python,
not \. In Python, and most other programming languages, \
starts an escape sequence, so to introduce a literal \, you
either need to prefix your string with r (r"\foo\bar") or double
your backslashes ("\\foo\\bar").
/ works fine on windows, and doesn't require escaping ("/foo/bar").
Depends on your definition of 'fine'.

'c:/temp\\COA.pdf',
'c:/temp\\job_setup.pdf']
Visually ugly, and a pain to compare files and paths.
I argue that the first is quite a bit more readable than the second:
'c:/temp/choose_python.pdf'
os.path.join([ 'c:', 'temp', 'choose_python.pdf' ])
I agree with your argument, but think that
r'c:\temp\choose_python.pdf'
is even more readable still. (Also, it wasn't I that suggested using
os.path.join() on everything.)
Also, heard of os.path.normpath? You probably shouldn't compare
pathnames without it.
Thanks -- I've heard of it (mostly in the context of resolving relative
path names (.. and such)), never checked it out... I'll read up on it.
