callable object that can be called with no parameters; each call to it should
return the next item in the iteration. When <em>callable</em> returns a value equal to
<em>sentinel</em>, the iteration will be terminated.</p>
<dd><p>Return true if the object <em>o</em> is an instance of a <aclass="reference internal" href="../builtins/stdtypes.html#range" title="range"><codeclass="xref py py-class docutils literal notranslate"><spanclass="pre">range</span></code></a> object.
<p>Do not create instances of these directly; prefer calling

<p>Note that there is no guarantee that a given built-in type uses a given iterator
type. For example, iterating over <aclass="reference internal" href="../builtins/stdtypes.html#range" title="range"><codeclass="xref py py-class docutils literal notranslate"><spanclass="pre">range</span></code></a> will use one of two iterator
types depending on the size of the range. Other types may start using a
similar scheme in the future, without warning.</p>
