escape single quote

[deep_logic]

Hi all,
I'm trying to do a simple chdir in IDLE, 2.7.5.

os.chdir(r'\\hilltop3\users$\LongRandy\My Documents\HOW-TO\'S)

I keep getting, "The system cannot find the path specified: "\\\\hilltop3\\users$\\LongRandy\\My Documents\\HOW-TO\\'s"

I did use the "\" single backslash just to try it and it does work if I'm just printing something.

Not sure what I'm getting wrong.

Any help is appreciated.
