title: Need to get names from a nested list in python
body: <p>Hi I have a simple nested list.
  My goal is to get items at index 0 of each inner list and assign it to a variable "names". So i want to have a variable with only names</p>
  
  <pre><code>numerical_list = [['Casey', 176544.328149], ['Riley', 154860.66517300002]]
  </code></pre>
  
  <p>Tried and failed</p>
  
  <pre><code>for i in numerical_list:
      list = i[0]
  
  new_list = [list]
  
  print(list)
  </code></pre>
  
  <p>Want:
  new_list to print out Casey, Riley</p>
