title: Python remainder operator
body: <p>Is there any remainder operator in Python? I do not ask for modulo operator, but remainder. For example:</p>
  
  <pre><code>-5 mod 2 = 1
  </code></pre>
  
  <p>but</p>
  
  <pre><code>-5 rem 2 = -1 # where "rem" is a remainder operator.
  </code></pre>
  
  <p>Do I have to implement it by myself ;)?</p>
