title: IndexError: list index out of range when composing dict from 2 column csv
body: <p>My script that crunches numbers stored in csv gets the numbers into a dict from the csv like this:</p>
  
  <pre><code>fide_rating_file = fide_csv_rating_file.read()
  fide_rating_file = fide_rating_file.split("\n")
  fide_rating_file2 = [f for f in fide_rating_file if len(f) &gt; 0]
  fide_rating_file3 = [f.split(",") for f in fide_rating_file2]
  fide_ratings = {f[0]: f[1] for f in fide_rating_file3}
  </code></pre>
  
  <p>This is probably not a pythonic way to work with csv (suggestions are welcome), I succesfully ran the script on tens of csv files. Now I am getting a traceback telling me that:</p>
  
  <pre><code>File "...script.py", line 76, in script
  fide_ratings = {f[0]: f[1] for f in fide_rating_file3}
  File "...script.py", line 76, in &lt;dictcomp&gt;
  fide_ratings = {f[0]: f[1] for f in fide_rating_file3}
  IndexError: list index out of range
  </code></pre>
  
  <p>The csv looks like this (this is just an excerpt, is way too long to post here):</p>
  
  <pre><code>1701991,2383
  1407589,2188
  1401815,2451
  1411802,1913
  1406248,2068
  504599,2134
  2252465,2099
  </code></pre>
  
  <p>The fact that it ran without errors on other files would suggest that this particular csv is corrupted. I checked for all inconsistencies I thought of compared to the rest of the files and found none. Thats why I am asking about the script here.</p>
