convert to list comprehension
<p>this is my python code </p>

<pre><code>mylist = ['a', 'f', 'z']
old_d = {'a': 'aaa', 'b': 'bbb', 'c': 'ccc', 'f': 'fff', 'g':'ggg', 'z':'zzz'} 
new_d = {}
for key in mylist:
    new_d[key] = old_d[key]
</code></pre>

<p>Can we write the above code using list comprehensions or something similar like </p>

<pre><code>new_d[key] = old_d[key] for key in mylist 
</code></pre>
