title: How to insert items in a dictionary against their respective keys
body: <p>Have a usecase where I want to add the list items to a dictionary and the list items will be used as a key value pair in the dictionary. For example</p>
  <p>Input list and dictionary</p>
  <p><code>list_Items = [[&quot;test1&quot;, &quot;test2&quot;, &quot;test3&quot;], [&quot;test4&quot;, &quot;test5&quot;, &quot;test6&quot;]]</code></p>
  <p><code>dict = {&quot;tire1&quot;: {}, &quot;tire2&quot;: {}}</code></p>
  <p>Expected output of print(dict)</p>
  <p><code>{&quot;tire1&quot;: {&quot;source&quot;: [&quot;test1&quot;, &quot;test2&quot;, &quot;test3&quot;]}, &quot;tire2&quot;: {&quot;source&quot;: [&quot;test4&quot;, &quot;test5&quot;, &quot;test6&quot;]}}</code></p>
  <p>Thanks</p>
