title: Set python variables to operators?
body: <h1>Python, Operators set to variables?</h1>
  
  <p>I am making a calculator and I want the user to be able to enter words like add to <code>+</code>. <br/> Is there any way to set python variables to operands. e.g.<br/></p>
  
  <pre><code>operands = {
      "add": +
  }
  </code></pre>
  
  <p>etc.
  <br/>
  Is there any way to do this <b> without modules</b>. But if not possible is there a module?</p>
