title: How do I count the trailing zeros in integer?
body: <p>I am trying to write a function that returns the number of trailing 0s in a string or integer. Here is what I am trying and it is not returning the correct values.</p>
  <pre><code>def trailing_zeros(longint):
      manipulandum = str(longint)
      x = 0
      i = 1
      for ch in manipulandum:
          if manipulandum[-i] == '0':
              x += x
              i += 1
          else:
              return x
  </code></pre>
