|
||
<p>我们在前面的课程中已经初步了解了列表和元组的相关知识。</p>
|
||
<p>我们也知道，列表还有元组没有的增删成员等功能。因此，本节课我们再来深入了解一下列表特有的一些知识点吧。</p>
|
||
<p>直接上代码例子：</p>
|
||
<pre class="language-"><code class="lang-python"><span class="token comment"># coding:utf-8</span>
|
||
<span class="token comment"># 增加列表元素，最最常用。列表有点像其他编程语言中所说的数组，但它支持多种类型的元素</span>
