<p>如果我从原始列表中删除了一个对象，如何才能使复制列表不发生更改？</p>
<p>原始列表</p>
<pre><code>[<Object.Object instance at 0x00EA29E0>, <Object.Object instance at 0x00EA2DC8>, <Object.Object instance at 0x00EA2EE0>]
</code></pre>
<p>弹出原始列表后复制列表（我希望此值等于上面的值）</p>
<pre><code>[<Object.Object instance at 0x00EA29E0>, <Object.Object instance at 0x00EA2DC8>]
</code></pre>
