And before generators come <em>iterables</em>.</p>\n\n<h2>Iterables</h2>\n\n<p>When you create a list, you can read its items one by one. Reading its items one by one is called iteration:</p>\n\n<pre><code>&gt;&gt;&gt; mylist = [1, 2, 3]\n&gt;&gt;&gt; for i in mylist:\n...    print(i)\n1\n2\n3\n</code></pre>\n\n<p><code>mylist</code> is an <em>iterable</em>. When you use a list comprehension, you create a list, and so an iterable:</p>\n\n<pre><code>&gt;&gt;&gt; mylist = [x*x for x in range(3)]\n&gt;&gt;&gt; for i in mylist:\n...    print(i)\n0\n1\n4\n</code></pre>\n\n<p>Everything you can use \"<code>for... in...</code>\" on is an iterable; <code>lists</code>, <code>strings</code>, files...</p>\n\n<p>These iterables
