body: <p>How to remove an element from an item in a list?</p>
  
  <p>normally when I delete something from a list I do:</p>
  
  <pre><code>df = [1,2,3,'name']
  df.remove('name') #output is [1,2,3]
  </code></pre>
  
  <p>but what if my entry isn't just a regular thing, for example:</p>
  
  <pre><code>df = [1,2,3, 'name 123']
  </code></pre>
  
  <p>and I want to get rid of the "_123"?</p>
