title: Removing a specific character from a text file
body: <p>I'm new to Python and coding generally, and I was doing a tiny project and I'm facing a problem:</p>
  
  <pre><code>44, 1, 6
  23, 2, 7
  49, 2, 3
  53, 2, 1
  68, 1, 6
  71, 2, 7
  </code></pre>
  
  <p>I just need to remove the 3rd and the 6th character from each line, or more specifically the "," characters from the whole file.</p>
  
  <p>and i need to do it using my python code </p>
  
  <pre><code>for line in my_file:
         ??????????????
  </code></pre>
  
  <p>Anything helps, thanks.</p>
