title: Int too large to convert to C long while doing .astype(int)
body: <p>I'm running a python script, where I have to convert a string column from a pandas <code>df</code> to <code>int</code>, using the <code>astype(int)</code> method. However, I get this following error:</p>
  
  <pre><code>"Python int too large to convert to C long"
  </code></pre>
  
  <p>My strings are all numbers in string format, up to 15 characters. Is there a way to convert this column to int type without this popping this error?</p>
