As it solved the problem  I put it as an answer   Don t use single and double quotes  especially when you define a raw string with r in front of it    The correct call is then  path   r C  Apps CorVu DATA Reports AlliD Monthly Commission Reports Output pdcom1    or   path   r C  Apps CorVu DATA Reports AlliD Monthly Commission Reports Output pdcom1

This is kind of an old question but I wanted to mentioned here the pathlib library in Python3  If you write  from pathlib import Path path  str    C   Users  myUserName  project  subfolder  osDir   Path path   or path  str    quot C   Users  myUserName  project  subfolder quot  osDir   Path path   osDir will be the same result  Also if you write it as  path  str    quot subfolder quot  osDir   Path path  absolutePath  str   str Path absolute osDir    you will get back the absolute directory as  C   Users  myUserName  project  subfolder   You can check more for the pathlib library here

I had a related issue working within Spyder  but the problem seems to be the relationship between the escape character        and the     in the path name Here s my illustration and solution  note single   vs double        path      C  Users myUserName project subfolder  path      C   Users  myUserName  project subfolder  os listdir path                 gives windows error path      C   Users  myUserName  project  subfolder  os listdir path                 gives expected behavior
