Say we have a list of <code>existing_ids</code> that we have already scraped. Let’s say we also have two lists, one of <code>names</code> and another of <code>urls</code> that correspond to <code>names</code> with the id of the names in the <code>url</code>.

Write a function <code>new_resumes</code> to return the names and ids for ids that we haven’t scraped yet.

Example:

Input:

<pre tabindex="0" class="chroma"><code>existing_ids = [15234, 20485, 34536, 95342, 94857]

names = [&#39;Calvin&#39;, &#39;Jason&#39;, &#39;Cindy&#39;, &#39;Kevin&#39;]
urls = [
 &#39;domain.com/resume/15234&#39;, 
 &#39;domain.com/resume/23645&#39;, 
 &#39;domain.com/resume/64337&#39;, 
 &#39;domain.com/resume/34536&#39;,
]
</code></pre>

Output:

<pre tabindex="0" class="chroma"><code>def new_resumes(existing_ids,names,urls) -&gt;
output = [(&#39;Jason&#39;, 23645), (&#39;Cindy&#39;, 64337)]
</code></pre>

Write a function to return the names and ids for ids that we haven't scraped yet.
