How to insert a list as a key in Python dictionary : <p>I'm using Python 3.5 and I want to know if its possible or if there's a way to use a list as a key in a dictionary in this way.</p>

<pre><code>dict = {['a', 'c', 'b']: 1, 
    ['a', 'b', 'c']: 2, 
    ['b', 'a', 'c']: 5}
</code></pre>

<p>I need so hard to work with lists as keys... </p>

<p>Thank you! </p>
