title: Python "0" to int
body: <p>I have a list with a string "0". When I execute my code I get an error because I want to convert this string to an int. </p>
  
  <pre><code>f = int(c[0])
  </code></pre>
  
  <blockquote>
    <p>ValueError: invalid literal for int() with base 10: ''</p>
  </blockquote>
  
  <p>Has someone an explanation? I need this 0.</p>
