title: Path in variable
body: <p>How can I add letter to path?</p>
  
  <p>For example if i have a path like <code>'c:\example2\media\uploads\test5.txt'</code> (stored in a variable), but I need something like <code>r'c:\example2\media\uploads\test5.txt'</code>, how can I add letter `r?</p>
  
  <p>Because the function <code>open()</code> does not want to open the first path. When I try add path to function <code>open()</code> it gives me an error and path like this: <code>u'c:\\example2\\media\\uploads\\test5.txt'</code> and says that file or directory is absent. What should i do?</p>
  
  <p>Error  looks like:</p>
  
  <pre><code>[Error 3] The system cannot find the path specified: u'C:\\example2\\media\\upload\\ZipFile.zip'
  </code></pre>
  
  <p>when i do this open('c:\example2\media\uploads\test5.txt') it not work. And gives me error ( which you can see on the top)</p>
