Converting List of 3 Element Tuple to Dictionary
<p>If I have two List of tuples </p>

<pre><code>tuple2list=[(4, 21), (5, 10), (3, 8), (6, 7)]

tuple3list=[(4, 180, 21), (5, 90, 10), (3, 270, 8), (6, 0, 7)]
</code></pre>

<p>How do I convert it to a dictionary as below,</p>

<pre><code>tuple2list2dict={4:21, 5:10, 3:8, 6:7}

tuple3list2dict={4: {180:21}, 5:{90:10}, 3:{270:8}, 6:{0:7}}
</code></pre>

<p>I know how to do it for 2 elements in tuples, using,</p>

<pre><code>tuple2list2dict=dict((x[0], index) for index,x in enumerate(tuple2list))
</code></pre>

<p>But for 3 elements I have problem, have error trying the below,</p>

<pre><code>tuple3list2dict=dict((x[0], dict(x[1], index)) for index,x in enumerate(tuple3list))
</code></pre>

<p>How do I reuse the above code for 3 element tuple to create a dictionary? </p>

<p>Any pointer appreciated or point me where I could read more on this. Have trouble finding it in the internet.</p>
