<h1 id="operator">operator</h1>
<p>The operator module exports a set of efficient functions corresponding to the intrinsic operators of Python. For example, <code translate="no" v-pre>operator.add(x, y)</code> is equivalent to the expression <code translate="no" v-pre>x+y</code>. Many function names are those used for special methods, without the double underscores.</p>
