title: Can't find my file with with open(filename, 'w') on Windows
body: <p>I'm studying python at school and I would like to test some scripts.
  However, the computers at school use Linux but at home I use Windows.
  I find my solution to practice at home but at least, my only problem is when I use <strong>with open</strong> to create a file in Python.</p>
  
  <p>The program works fine because I verify the correction at school but I can't find my file on my computer.</p>
  
  <p>The program I work on is to clean a text without space or "#" so I just put the list lines here :</p>
  
  <pre><code>with open(deck, 'r') as data: 
      with open('output.txt', 'w') as output: 
          for line in data: 
              if (not ligne_commentee(line)) and (not ligne_vide(line)):
                  output.write(supprime_caracteres_commentes(line))
  </code></pre>
  
  <p>PS : I'm french, so the names of the file are in french...</p>
  
  <p>Deck is <code>deck = "C:\Users\CHLOE\Desktop\mes\texte_test.txt"</code>.</p>
  
  <p>This is how I can read my file but I don't find a solution to find the find I create with <code>output.write()</code>.</p>
  
  <p>Can you help me ? Thank you !</p>
