How to return key if a given string matches the keys value in a dictionary
<p>I am new to dictionaries, and i'm trying to find out how to return a key if a given string matches the keys value in a dictionary.</p>

<p>Example:</p>

<pre><code>dict = {"color": (red, blue, green), "someothercolor": (orange, blue, white)}
</code></pre>

<p>I want to return <code>color</code> and <code>someothercolor</code>, if the key's value contains <code>blue</code>.</p>

<p>Any suggestions? </p>
