title: Python error "IOError: [Errno 2] No such file or directory" but file is there
body: <p>I am trying to read a csv file and I am getting the error above but the file is there.    The line giving the error is</p>
  
  <pre><code>infilequery = file('D:\x88_2.csv','rb')
  </code></pre>
  
  <p>and I get the error below.</p>
  
  <p>Traceback (most recent call last):
    File "C:\Python26\usrapply_onemol2.py", line 14, in 
      infilequery = file('D:\x88_2.csv','rb') 
  IOError: [Errno 2] No such file or directory: 'D:\x88_2.csv'</p>
  
  <p>I can put a file from the same directory in its place and python at least sees it.  The result of os.listdir("D:") features 'x88_2.csv' and the result of "dir D:\" also includes it.  When putting the filename in and allowing python to complete the path and selecting x88_2.csv from the dropdown, I still get the same error.  What is up here?</p>
