</code></pre><p>三个参数代表的含义是最小值，最大值，步长，并且遵循“左闭右开”的惯例。</p><p>中午吃什么：</p><pre><code class="language-python">lunches = ['肉夹馍','火锅','刀削面','炒年糕','麻辣香锅','烤肉饭']

for lunch in lunches:
    print(f"吃 {lunch}")
</code></pre><h2>两个循环控制关键字</h2><p><code>continue</code> 与 <code>break</code> 是两个控制循序执行流程的关键字，具体功能如图所示：</p><p><img src="https://sophia-1303119720.cos.ap-nanjing.myqcloud.com/continue_break.png" alt="continue_break" title=""></p><p>与其他语言类似。</p>
